agree, that would take the 'S' out of it.

i think that how to deal with this should be left to the host; possibly
with a LADSPA_HINT_UNBUFFERED_CONTROL.

yeah, let's keep it real simple and export:
const char * xml_spec;
and we can translate all discussions about ontologies, guis etc into a
less harmful discussion about the semantics of this xml_spec, which
i'd imagine to be roughly like:
<typeOf>
waveshaper
frequency-effect
</typeOf>
and future enhancements may come at a lesser price than a revised <ladspa.h>.
if a host does not understand a tag, he may just skip it. 't would also
allow for the 'quick action wanted' in the subject line :)
