using the following URIs in the UI's RDF data:
<pre>
uiext:portNotification
uiext:noPortNotification
uiext:plugin
uiext:portIndex
</pre>
For example, if you want the UI with uri
<code><http://my.pluginui></code> for the plugin with URI
<code><http://my.plugin></code> to get notified when the value of the
output control port with index 4 changes, you would use the following
in the RDF for your UI:
<pre>
<http://my.pluginui> uiext:portNotification [ uiext:plugin <http://my.plugin> ;
uiext:portIndex 4 ] .
</pre>
and similarly with <code>uiext:noPortNotification</code> if you wanted
to prevent notifications for a port for which it would be on by default
otherwise. The UI is not allowed to request notifications for ports of
types for which no transfer mechanism is specified, if it does it should
be considered broken and the host should not load it.

The @c buffer is only valid during the time of this function call, so if
