Hi Bob,

Thanks for volunteering. Yes. I agree this would be a new 6.3 section. You
should also update the non-normative sections for 1.2.1 & 1.2.2. I suspect
that this may also spawn discussions around text in sections 2.3, 2.4, 2.5,
& 6. If changes need to be made here please keep in mind the constraints of
mobile devices, hardware decoders, and what the UA is supposed to do if it
can't handle extra tracks. If possible, I'd really like to keep this to a
minimal viable feature set instead of allowing absolutely everything that
is possible in MPEG2-TS. I think that will go a long way towards
guarenteeing interoperable implementations.
