-<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>

-    lv2:documentation """
-<p>Predicate to relate a plugin instance to an InstanceState. This may be used
-wherever the state of a particular plugin instance needs to be represented.
-Note that the domain of this property is unspecified, since LV2 does not define
-any RDF class for plugin instance. This predicate may be used wherever it makes
-sense to do so, e.g.:</p>
-<pre class="turtle-code">
-@prefix eg: &lt;http://example.org/&gt; .
-
-&lt;plugininstance&gt; state:instanceState [
-    eg:somekey "some value" ;
-    eg:someotherkey "some other value" ;
-    eg:favourite-number 2
-] .
-</pre>
-<p>Note that this property is provided because it may be useful for hosts,
-plugins, or extensions that work with instance state, but its use is not
-required to support the LV2 State extension.</p>
