Your problem is implementation, not standardisation. The construct you use is correct according to the SMIL 3.0 spec. But: I = know of no SMIL players that actually implement the=20 clipBegin=3D"marker=3D#foo" functionality. In addition, the SMIL spec is = vague (and intentionally so) as to what the external representation of markers is. Ambulant has some minimal support for markers, but (a) only for markers = defined in SmilText files, and (b) only for used in event-based timing. Adding support to Ambulant for markers in the way you sketch shouldn't = be too hard: the infrastructure is all in place. But: we (the CWI ambulant team) don't have the time for this, and no = compelling use case right now that will let us make time. But if you have the developer capabilities yourself we are = (as always) more than willing to help.
