-/** @file
- * This is an LV2 extension allowing plugin instances to have a set of
- * dynamic named/typed variables (ie key/value metadata).
- *
- * Plugin variable values are always in string form (if numeric
- * variable values are requires in realtime run callbacks, it is assumed
- * the plugin will cache the converted value).
- *
- * Keys are strings, either free-form locally unique strings, or URIs.
- * Types are URIs (corresponding to some type defined somewhere, e.g. in an
- * XML namespace or RDF ontology).
- *
- * The goal is to provide a powerful key/value system for plugins, which is
- * useful for setting run-time values (analogous to DSSI's "configure" calls)
- * which is typed and ideal for serializing to RDF (which means variable
- * values can be stored in the same file as the plugin's definition) or
- * network transmission/control.

-An extension for setting named/typed variables on an instance of an
-LV2 Plugin (or anything else).  A "variable" is really just a (reified)
-RDF statement with an implicit subject (e.g. the plugin instance).
-
-Variables serve as a portable, network transparent, and serialisable
-mechanism for clients (e.g. user interfaces, programs) to control any
-parameter of a running plugin instance.  Because variables are 'keyed'
-by URI (the predicate), future extensions can define variables with
-specific meanings or restricted/extended types.
-The value (rdf:value) of a variable may be anything, but hosts or plugins
-aren't guaranteed to support anything other than simple typed literals.
-Serialisation and code access to complex variables is considered outside
-the scope of this extension.
-
-Hosts and plugins SHOULD use the following types for appropriate values:
-
-<table>
-<tr><th>RDF Type</th><th>Data Type</th></tr>
-<tr><td>xsd:string</td><td>string</td></tr>
-<tr><td>xsd:decimal</td><td>floating point number</td></tr>
-<tr><td>xsd:integer</td><td>integer number</td></tr>
-<tr><td>xsd:boolean</td><td>boolean value</td></tr>
-</table>
-
-This extension does not currently define a code mechanism for access
-to variables.  A future revision, or a different extension, may.
-
-An example of a plugin with several variables:
-<pre>
-&lt;http://example.org/plugin&gt; a lv2:Plugin ;
-	lv2var:variable [
-		rdf:predicate &lt;http://example.org/greetingology#Greeting&gt; ;
