+<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
+<pre>
+  @prefix ui: &lt;http://lv2plug.in/ns/ext/ui#&gt;.
+  &lt;http://my.pluginui&gt;  a             ui-gtk:GtkUI;
+                        lv2:appliesTo &lt;http://my.plugin&gt;;
+                        ui:binary     &lt;myui.so&gt;.
+</pre>
+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. 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 ui:UI, in this case ui-gtk:GtkUI. 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 <b>not</b> 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 lv2_ui.h is all you can expect to work.

+<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:
+<pre>
+    rdf:type (with object a proper subclass of ui:UI)
+    doap:name (one without language tag)
+    lv2:binary (with a shared object file as object)
+    lv2:appliesTo (with a LV2 plugin as object)
+</pre>
+The rdf:type of an UI is used by the host to decide whether it supports the
+UI and how to handle the LV2_UI_Widget object that is returned by the UIs
+get_widget() function. For example, a type of ui-gtk:GtkGUI might tell the host
+that LV2_UI_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 it's required features, and an UI MUST fail to
+instantiate if the host doesn't pass all required features to instantiate().
