-/** @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.
