+<p>This extension defines a generic format for a typed piece of data, called an
+lv2:Atom (e.g. integers, strings, buffers, data structures,
+etc). Atoms allow LV2 plugins and hosts to communicate, process, serialise,
+and store values of any type via a generic mechanism (e.g. LV2 ports, events,
+disk, shared memory, network). Atoms are, with one exception, Plain
+Old Data (POD) and may be safely copied (e.g. with a simple call to
+<code>memcpy</code>).</p>
+
+<p>Since Atom communication can be implemented generically, plugins that
+understand some type can be used together in a host that does not understand
+that type, and plugins (e.g. routers, delays) can process atoms of unknown
+type.</p>
+
+<p>An Atom can be trivially constructed in-place from an
+<a href="http://lv2plug.in/ns/ext/event#Event">Event</a> as defined by the
+<a href="http://lv2plug.in/ns/ext/event">LV2 Event</a> extension. In other
+words, an Event is simply an Atom with a time stamp header. Atoms SHOULD
+be used anywhere a "value" needs to be stored or communicated, to allow
+implementations to be polymorphic and extensible.</p>
+
+<p>Atoms (the start of the LV2_Atom header) MUST be 32-bit aligned.</p>
+
+<p>Atoms can be communicated in many ways. Since an Atom is the payload of an
+Event, an <a href="http://lv2plug.in/ns/ext/event#EventPort">EventPort</a> can
+be used for communicating Atoms in realtime with sub-sample time stamp
+accuracy. This extension also defines two port types for connecting directly
+to a single Atom: atom:ValuePort and atom:MessagePort, which both have the same
+buffer format but different semantics (with respect to how the run() callback
+interprets the Atom).</p>
+
+<p>Implementing this extension requires a facility for mapping URIs to
+integers, such as the <a href="http://lv2plug.in/ns/ext/urid">LV2 URID</a>
+extension.</p>

+multiple threads. Contexts can be used to add non-realtime functionality
+to a plugin while still keeping the audio run() method realtime safe.</p>
+
+<p>A context is an LV2 feature, so the usual LV2 feature mechanism is used
+to determine whether a plugin has a given context, and whether or not it is
+mandatory.</p>
+
+<p>Unless otherwise stated, each context (defined by some URI) adds a new
+threading class similar to the Audio class defined by LV2. Each context has a
+run callback and a connect_port callback both in the same class (i.e. can't be
+called concurrently), but may be called concurrently with functions for other
+contexts (excluding the Instantiation class). Context properties such as
+ctx:hardRTCapable apply to both functions.
+The host MUST only call the correct connect_port function associated with the
+context for that port, i.e. it is an error to use the main LV2 connect_port
+function on a port with a context other than the main LV2 run function.</p>

+ lv2:documentation """
+<p>The LV2 API, on its own, cannot be used to write plugin libraries where data
+is dynamically generated at runtime (e.g. API wrappers), since LV2 requires
+needed information to be provided in one or more static data (RDF) files. This
+API addresses this limitation by extending the LV2 API.</p>
+
+<p>To detect that a plugin library implements a dynamic manifest generator,
+the host checks its static manifest for a description like:</p>
+
+<pre class="turtle-code">
+&lt;http://example.org/my-dynamic-manifest&gt;
+ a dman:DynManifest ;
+ lv2:binary &lt;mydynmanifest.so&gt; .
+</pre>
+
+<p>To load the data, the host loads the library
+(e.g. <code>mydynmanifest.so</code>) as usual and fetches the dynamic Turtle
+data from it using this API.</p>
+
+<p>The host is allowed to request regeneration of the dynamic manifest multiple
+times, and the plugin library is expected to provide updated data if/when
+possible. All data and references provided via this API before the last
+regeneration of the dynamic manifest is to be considered invalid by the host,
+including plugin descriptors whose URIs were discovered using this API.</p>
+
+<h3>Accessing Data</h3>
+
+<p>Whenever a host wants to access data using this API, it could:</p>
+
+<ol>
+<li>Call lv2_dyn_manifest_open().</li>
+<li>Create a FILE for functions to write data to (e.g. using tmpfile()).</li>
+<li>Get a <q>list</q> of exposed subject URIs using
+ lv2_dyn_manifest_get_subjects().</li>
+<li>Call lv2_dyn_manifest_get_data() for each URI of interest to
+ get the data related to that URI (which can be written to any FILE).</li>
+<li>Call lv2_dyn_manifest_close().</li>
+<li>Parse the content of the FILE(s).</li>
+<li>Free/delete/unlink the FILE(s).</li>
+</ol>
+
+<p>Each call to the above mentioned dynamic manifest functions MUST write a
+complete, valid Turtle document (including all needed prefix definitions) to
+the output FILE.</p>
+
+<p>Each call to lv2_dyn_manifest_open() causes the (re)generation of the
+dynamic manifest data, and invalidates all data fetched before the call.</p>
+
+<p>In case the plugin library uses this same API to access other dynamic
+manifests, it MUST implement some mechanism to avoid potentially endless loops
+(such as A loads B, B loads A, etc.) and, in case such a loop is detected, the
+operation MUST fail. For this purpose, use of a static boolean flag is
+suggested.</p>
+
+<h3>Threading Rules</h3>
+
+<p>All of the functions defined by this specification belong to the Discovery
+class.</p>

+<p>This extension provides a mechanism for plugins to portably refer to files
+in persistent plugin state (using the <a
+href="http://lv2plug.in/ns/ext/persist">LV2 Persist</a> extension), and create
+instance-local files in host-defined locations (e.g. for recording).</p>
+
+<p>The motivating idea behind this extension is that all details of file
+management MUST be handled by the host since different hosts may have very
+different requirements. Plugins MUST NOT make any assumption about file system
+locations beyond what is explicitly guaranteed by this extension.</p>
+
+<p>This extension defines two features: files:newFileSupport allows plugins to
+create new files within an instance-specific namespace at any time (except in
+realtime contexts); while files:pathSupport allows plugins to refer to file
+paths in plugin state in a way transparent to the host.</p>
+
+<p>To create a new file, the plugin MUST request a path from the host using
+LV2_Files_New_File_Support::new_file_path(). Thus, the host may choose an
+appropriate location for the file (e.g. a writable path on the appropriate disk
+volume or a path within a session directory) using information not available to
+the plugin.</p>
+
+<p>To store a path in persistent state, the plugin MUST map it to an
+<q>abstract path</q> using LV2_Files_Path_Support::abstract_path(). To use a
+path loaded from persistent state, the plugin MUST map the (abstract) path to
+an absolute path using LV2_Files_Path_Support::absolute_path(). Thus, the host
+can manage all paths used in a session and support exporting sessions to a
+portable self-contained format for archival or distribution.</p> """ .

+<p>This feature allows plugins to refer to pre-existing or newly created files

+LV2_FILES_PATH_SUPPORT_URI and LV2_Feature::data pointed to an instance of

+
+<p>Abstract paths reside in a namespace specific to a plugin instance.

+<p>This extension defines an interface that can be used to create UIs for
+plugins. The UIs are code that reside in shared object files in an LV2
+bundle and are referenced in the RDF data using the triples:</p>
+<pre class="turtle-code">
+@prefix pui: &lt;http://lv2plug.in/ns/ext/pui#&gt; .
+&lt;http://example.org/my-ui&gt; a pui:Gtk2UI ;
+ lv2:appliesTo &lt;http://example.org/my-plugin&gt; ;
+ pui:binary &lt;my-ui.so&gt; .
+</pre>
+<p>... where <code>http://example.org/my-plugin</code> is the URI of the plugin,
+<code>http://example.org/my-ui</code> is the URI of the plugin UI and
+<code>my-ui.so</code> is the relative URI to the shared object file. While it
+is possible to have the plugin UI and the plugin in the same shared object file
+it is probably a good idea to keep them separate so that hosts that don't want
+UIs don't have to load the UI code.</p>
+
+<p>A UI MUST specify its class in the RDF data and the class MUST be a proper
+subclass of pui:UI, in this case pui:Gtk2UI. The class defines what type the
+UI is, e.g. what graphics toolkit it uses. There are no UI classes defined in
+this extension, those are specified separately (and anyone can define their
+own).</p>
+
+<p>It's entirely possible to have multiple UIs for the same plugin, or to have
+the UI for a plugin in a different bundle from the actual plugin - this way
+people other than the plugin author can write plugin UIs independently without
+editing the original plugin bundle. It is also possible to have one UI that
+works with several different plugins.</p>
+
+<p>UIs should also be written in such a way that the host may load several
+instances of an UI, or different UIs, and use them with the same plugin
+instance.</p>
+
+<p>Note that the process that loads the shared object file containing the UI
+code and the process that loads the shared object file containing the actual
+plugin implementation do not have to be the same. There are many valid reasons
+for having the plugin and the UI in different processes, or even on different
+machines. This means that you can <strong>not</strong> use singletons and
+global variables and expect them to refer to the same objects in the UI and the
+actual plugin. The function callback interface defined in the header pui.h is
+all you can expect to work.</p>

+<p>The class which represents an LV2 plugin UI.
+</p>
+
+<p>To be used by a host a UI MUST have at least the following properties:</p>

+<li>rdf:type (with object a proper subclass of pui:UI)</li>
+<li>doap:name (one without language tag)</li>
+<li>lv2:binary (with a shared object file as object)</li>
+<li>lv2:appliesTo (with a LV2 plugin as object)</li>
+</ul>
+
+<p>The rdf:type of an UI is used by the host to decide whether it supports the
+UI and how to handle the LV2_PUI_Widget object that is returned by the UIs
+get_widget() function. For example, a type of pui:Gtk2UI might tell the
+host that LV2_PUI_Widget is a pointer to an object of a type defined in the
+Gtk+ library. No UI types are defined in this extension, that is intentionally
+left for other extensions.</p>
+
+<p>The doap:name property should be at most a few words in length using title
+capitalization, e.g. "Flashy Mixer GUI". Use lv2:documentation for more
+detailed descriptions.</p>
+
+<p>UIs may have optional or required features, specified using lv2:optionalFeature
+or lv2:requiredFeature. The same rules apply here as for plugins; a host MUST
+pass the LV2_Feature objects for all features it supports to the UI's
+instantiate() function, a host SHOULD NOT try to instantiate an UI if it
+doesn't support all of its required features, and an UI MUST fail to
+instantiate if the host doesn't pass all required features to instantiate().

+ lv2:documentation """
+<p>This extension provides a mechanism for plugins to save and restore state
+across instances, allowing hosts to save, restore, clone, or take a snapshot of
+a plugin instance's state at any point in time. The intention is for a plugin
+instance's state to be <em>completely</em> described by port values (as with all
+LV2 plugins) and a simple dictionary.</p>
+
+<p>The <q>state</q> described by this extension is conceptually a single
+key/value dictionary, where keys are URIDs and values are type-tagged blobs of
+any type. The plugin provides an LV2_State_Interface for working with this
+state. To save or restore, the host calls LV2_State_Interface::save() or
+LV2_State_Interface::restore(), passing a callback to be used for handling a
+single key/value pair. The host is free to implement saving and restoring in
+any way; the actual mechanism is completely abstract from the plugin's
+perspective.</p>
+
+<p>Because state is a simple dictionary, hosts and plugins can work with it
+easily from many languages and protocols. Keys are URIDs for performance
+reasons as well as RDF compatibility, which makes it simple to serialise state
+in many formats (e.g. any RDF syntax, JSON, XML, key/value databases such as
+BDB, etc.). In particular, state can be elegantly described in a plugin's
+Turtle description, which is useful for e.g. presets or default state.
+Specific keys may be described in Turtle on the fly or in extensions,
+allowing plugins to use common well-defined keys.</p>
+
+<p>This extension defines a conceptual model of state and a mechanism for
+saving and restoring it, but no interface for manipulating it dynamically.
+While no such mechanism is defined here, dynamic control of plugins SHOULD be
+achieved by generic manipulations of the same conceptual state dictionary used
+by this extension (e.g. <code>plugin->set(key, value)</code>). Accordingly,
+plugins SHOULD use meaningful and well-defined keys wherever possible.</p>
+
+<p>In pseudo code, a typical use case in a plugin is:</p>
+<pre class="c-code">
+#define NS_EG "http://example.org/"
+#define NS_ATOM "http://lv2plug.in/ns/ext/atom#"

+

+<h4>UI issues</h4>
+<p>When using port_event / write_port (and possible other communication
+mechanisms), the format parameter should contain the numeric value of URI
+LV2_STRING_PORT_URI (mapped with http://lv2plug.in/ns/extensions/ui specified
+as map URI).</p>

+&lt;http://lv2plug.in/ns/ext/contexts#MessageContext&gt; for transfer. However,
+contexts mechanism does not offer any way to notify the message recipient about
+which ports have been changed. To remedy that, this extension defines a flag
+LV2_STRING_DATA_CHANGED_FLAG that carries that information inside a port value
+structure.</p>
+
+<h4>Storage</h4>
+<p>The value of string port are assumed to be "persistent": if a host saves and
+restores a state of a plugin (e.g. control port values), the values of input
+string ports should also be assumed to belong to that state. This also applies
+to message context: if a session is being restored, the host MUST resend the
+last value that was sent to the port before session has been saved. In other
+words, string port values "stick" to message ports.</p>

+ lv2:documentation """
+<p>This extension defines an interface that can be used in LV2 plugins and
+hosts to create UIs for plugins. The UIs are similar to plugins and reside in
+shared object files in an LV2 bundle. UIs are associated with a plugin in RDF
+using the triples:</p>
+
+<pre class="turtle-code">
+@prefix ui: &lt;http://lv2plug.in/ns/extensions/ui#&gt; .
+
+&lt;http://my.plugin&gt; ui:ui &lt;http://my.pluginui&gt; .
+&lt;http://my.pluginui&gt; a ui:GtkUI ;
+ ui:binary &lt;myui.so&gt; .
+</pre>
+
+<p>where &lt;http://my.plugin&gt; is the URI of the plugin,
+&lt;http://my.pluginui&gt; is the URI of the plugin UI and &lt;myui.so&gt; is
+the relative URI to the shared object file.</p>
+
+<p>While it is possible to have the plugin UI and the plugin in the same shared
+object file it is probably a good idea to keep them separate so that hosts that
+don't want UIs don't have to load the UI code. A UI MUST specify its class in
+the RDF data (ui:GtkUI in the above example). The class defines what type the
+UI is, e.g. what graphics toolkit it uses. Any type of UI class can be defined
+separately from this extension.</p>
+
+<p>It is possible to have multiple UIs for the same plugin, or to have the UI
+for a plugin in a different bundle from the actual plugin - this way people
+other than the plugin author can write plugin UIs independently without editing
+the original plugin bundle.</p>
+
+<p>Note that the process that loads the shared object file containing the UI
+code and the process that loads the shared object file containing the actual
+plugin implementation are not necessarily the same process (and not even
+necessarily on the same machine). This means that plugin and UI code can
+<strong>not</strong> use singletons and global variables and expect them to
+refer to the same objects in the UI and the actual plugin. The function
+callback interface defined in this header is the only method of communication
+between UIs and plugin instances (extensions may define more, though this is
+discouraged unless absolutely necessary since the significant benefits of
+network transparency and serialisability are lost).</p>
+
+<p>Since the LV2 specification itself allows for extensions that may add new
+functionality that could be useful to control with a UI, this extension allows
+for meta-extensions that can extend the interface between the UI and the
+host. These extensions mirror the extensions used for plugins - there are
+required and optional "features" that you declare in the RDF data for the
+UI:</p>
+
+<pre class="turtle-code">
+&lt;http://my.pluginui&gt; lv2:requiredFeature &lt;http://my.feature&gt; .
+&lt;http://my.pluginui&gt; lv2:optionalFeature &lt;http://my.feature&gt; .
+</pre>
+
+<p>The rules for a UI with a required or optional feature are identical to
+those of lv2:Plugin instances: if a UI declares a feature as required, the host
+is NOT allowed to load it unless it supports that feature; and if it does
+support a feature, it MUST pass an appropriate LV2_Feature struct to the UI's
+instantiate() method. These features may be used to specify how to pass
+specific types of data between the UI and the plugin port buffers (see
+LV2UI_Write_Function for details).</p>
+
+<p>UIs written to this specification do not need to be threadsafe - the
+functions defined below may only be called in the same thread the UI main loop
+is running in.</p>
+
+<p>Note that this UI extension is NOT a lv2:Feature. There is no way for a
+plugin to know whether the host that loads it supports UIs or not, and the
+plugin must always work without the UI (although it may be rather useless
+unless it has been configured using the UI in a previous session). From the
+plugin perspective, control from a UI is the same as control from anywhere else
+(e.g. the host, the user): via ports.</p>
+
+<p>A UI does not have to be a graphical widget, it could just as well be a
+server listening for OSC input or an interface to some sort of hardware device,
+depending on the RDF class of the UI.</p>

+As with most build systems, building and installing a project with waf is done
+in three separate stages:
+
+Configure: ./waf configure [OPTIONS]
+ e.g.: ./waf configure --prefix=/some/where
+
+ The default prefix is /usr/local
+
+
+Build: ./waf [OPTIONS]
+ e.g.: ./waf
+
+
+Install: ./waf install [OPTIONS]
+ e.g.: ./waf install
+ e.g.: DESTDIR=/home/drobilla/packages ./waf install
+
+ The environment variable DESTDIR can be used to add any prefix to
+ the install paths (useful for packaging).
+
+
+Run './waf --help' for detailed option information.

+LV2
+---
+
+LV2 gives programmers the ability to write audio processors (or "plugins") in
+C/C++ which can be dynamically loaded into a range of applications (or
+"hosts").
+
+This core specification is deliberately as short and simple as possible, but is
+designed so that extensions can be defined to add more advanced features.
+
+More information about LV2 can be found at <http://lv2plug.in>.
+
+Applications that use LV2 plugins should depend on this package. It includes a
+header, LV2 bundle, and a pkg-config file. To compile against LV2, build
+scripts should check for the pkg-config package "lv2core", or simply check for
+the header "lv2/lv2plug.in/ns/lv2core/lv2.h".
+
+The appropriate C include for LV2 specifications is based on their URI, e.g.:
+
+#include "lv2/lv2plug.in/ns/lv2core/lv2.h"
+
+Is how code should include the header "lv2.h" in this bundle, which defines the
+specification with URI "http://lv2plug.in/ns/lv2core". Other specifications
+should follow this convention, e.g. the correct way to include the header
+"foo.h" in the extension "http://example.org/foo" is:
+
+#include "lv2/example.org/foo/foo.h"
+
+Please package these components in a single package (e.g. do not split the
+headers, data, and program into separate packages). This package, in its
+entirety, is a build and run time dependency of any code that uses LV2.
+Distributions are encouraged to include it with package name "lv2core".

+<p>LV2 is an interface for writing audio processors, or <q>plugins</q>, in
+C/C++ which can be dynamically loaded into many applications, or <q>hosts</q>.
+This <q>core</q> specification is simple and minimal, but is designed so that
+<q>extensions</q> can be defined to add more advanced features, making it
+possibly to implement nearly any feature imaginable.</p>
+
+<p>LV2 maintains a strong distinction between <q>code</q> and <q>data</q>.
+Plugin code is in a shared library, while data is in a companion data file
+written in <a href="http://www.w3.org/TeamSubmission/turtle/">Turtle</a>.
+Code, data, and any other resources (e.g. waveforms) are shipped together in a
+<q>bundle</q> directory. The code contains only the executable portions of the
+plugin which inherently <em>must</em> be written in code. All other data is
+provided in the data file(s). This makes plugin data flexible and extensible,
+and allows the host to do everything but run the plugin without loading or
+executing any code. Among other advantages, this makes hosts more robust
+(broken plugins can't crash a host during discovery) and allows generic tools
+and non-C programs to work with LV2 data. LV2 itself and extensions are
+distributed in a similar way.</p>
+
+<p>An LV2 plugin library is suitable for dynamic loading (e.g. via
+<code>dlopen()</code>) and provides one or more plugin descriptors via the
+<code>lv2_descriptor()</code> function. These can be instantiated to create
+plugin <q>instances</q>, which can be run directly on data or connected
+together to perform advanced signal processing tasks.</p>
+
+<p>Plugins communicate via <q>ports</q>, which can transmit any type of data.
+Data is processed by first <q>connecting</q> each port to a buffer, then
+repeatedly calling a plugin's <code>run()</code> method to process blocks of
+data.</p>
+
+<p>This core specification defines two types of port, equivalent to those in <a
+href="http://www.ladspa.org/">LADSPA</a>: lv2:ControlPort and lv2:AudioPort.
+Audio ports contain arrays with one <code>float</code> element per sample,
+allowing a block of audio to be processed in a single call to
+<code>run()</code>. Control ports contain single <code>float</code> values,
+which are fixed and valid for the duration of the call to <code>run()</code>.
+Thus the <q>control rate</q> is determined by the block size, which is
+controlled by the host (and not necessarily constant).</p>
+
+<h3>Threading Rules</h3>
+
+<p>To faciliate use in multi-threaded programs, LV2 functions are partitioned
+into several threading classes:</p>
+
+<table>
+<tr><th>Discovery Class</th>
+ <th>Instantiation Class</th>
+ <th>Audio Class</th></tr>
+<tr><td>lv2_descriptor()</td>
+ <td>LV2_Descriptor::instantiate()</td>
+ <td>LV2_Descriptor::run()</td></tr>
+<tr><td>LV2_Descriptor::extension_data()</td>
+ <td>LV2_Descriptor::cleanup()</td>
+ <td>LV2_Descriptor::connect_port()</td></tr>
+<tr><td></td><td>LV2_Descriptor::activate()</td><td></td></tr>
+<tr><td></td><td>LV2_Descriptor::deactivate()</td><td></td></tr>
+</table>
+
+<p>The rules that hosts MUST follow are:</p>
+<ul>
+<li>When any function is running for a plugin instance,
+no other function in the same class may run for that instance.</li>
+<li>When a <em>Discovery</em> function is running,
+no other functions in the same shared object file may run.</li>
+<li>When an <em>Instantiation</em> function is running for a plugin instance,
+no other functions for that instance may run.</li>
+</ul>
+
+<p>Any simultaneous calls that are not explicitly forbidden by these rules are
+allowed. For example, a host may call <code>run()</code> for two different
+plugin instances simultaneously.</p>
+
+<p>Plugin functions in any class MUST NOT manipulate any state which might
+affect other plugin or host code, e.g. by using non-reentrant global
+functions.</p>
+
+<p>Extensions to this specification which add new functions MUST declare in
+which of these classes the functions belong, define new classes for them, or
+otherwise precisely describe their threading rules.</p>

+<p>The minor version of an LV2 Resource. This property is used (along with
+lv2:microVersion) by hosts to distinguish different versions of a compatible
+resource, e.g. to load only the bundle with the most recent version.</p>
+
+<p>The version of an LV2 resource is composed of two fields: minor version,
+and micro version. These have the usual semantics:</p>
+
+<ul>
+<li>The minor version MUST be incremented when backwards (but not
+forwards) compatible additions are made, e.g. the addition of a port to a
+plugin.</li>
+
+<li>The micro version is incremented for changes which do not affect
+compatibility at all, e.g. bug fixes or documentation updates.</li>
+</ul>
+
+<p>Note there is deliberately no concept of a major version: all versions of an
+LV2 resource with a given URI are by definition backwards compatible. More
+precisely: replacing a resource with a newer version of that resource MUST NOT
+break anything. If a change is made which breaks this rule, the URI
+of the resource MUST be changed. In contexts where a full (e.g. <a
+href="http://semver.org">SemVer</a> conformant) version number is required, the
+major version of all released LV2 resources is 1.</p>
+
+<p>Plugins and extensions MUST adhere to the following rules:</p>
+<ul>
+<li>All versions of a plugin with a given URI MUST have the <q>same</q> set of
+mandatory (i.e. not lv2:connectionOptional) ports with respect to lv2:symbol
+and rdf:type. In other words, every port on a specific version of a plugin has
+a lv2:symbol and a set of rdf:types; all future versions of that plugin are
+guaranteed to have a port with the same lv2:symbol and at least those
+rdf:types. New types may be added only if doing so does not break
+compatibility, i.e. if old hosts will continue to work correctly with the new
+plugin.</li>
+
+<li>New ports MAY be added without changing the plugin URI if and only if they
+are lv2:connectionOptional and the minor version is incremented.</li>
+
+<li>The minor version MUST be incremented if the index of any port (identified
+by its symbol) is changed.</li>
+
+<li>All versions of an extension MUST be compatible in the sense that an
+implementation of the new version can interoperate with an implementation of
+any previous version.</li>
+</ul>
+
+<p>(Note these rules are not necessarily exhaustive)</p>
+
+<p>Anything that depends on a specific version of a plugin (e.g. a
+serialisation that references ports by index) MUST refer to the plugin by both
+URI and version. However, implementations should be tolerant and extensions
+should be designed such that there is no need to do this (e.g. indices should
+only be meaningful for a particular plugin <em>instance</em> at run-time).</p>
+
+<p>When hosts discover several installed versions of a resource, they SHOULD
+warn the user and load only the most recent version.</p>
+
+<p>An odd minor <em>or</em> micro version indicates that the resource is a
+possibly unstable development version. Hosts and tools SHOULD clearly indicate
+this wherever appropriate. Several versions of a resource with an odd version
+may exist; i.e. it is acceptable to work on a development version of a resource
+(e.g. in source control) without worrying about version numbers as long as
+either the minor or micro version is odd.</p>
