[gst-devel] GstPolyBin idea and request for comments

A flag for GstController makes sense since many elements might need it,
however this sounds like a flag just for PolyBin elements which is getting
a bit specialised.

Instead of adding another flag just for PolyBin, you could just document
the naming convention for the properties so the app can introspect what
each property does, for example:
foo_global - a global property which acts on all voices
foo_voice_003 - a property which acts on voice 3 of the PolyBin
