Sorensen-3 (stsd), MPEG-4 video/audio (esds). Maybe more...

Behaviour should be "sink pad receives it if source pad provides it; it is always optional (even though things might not work without ;) ); sink or source pad template may never enlist it since it is optional; if the property is provided by the source pad, it should always do so fixed".

That way, the whole fixation process will not apply here.
