tts:dynamicFlow - need to clarify what timeline is used by flow timers in B.5

State:

CLOSED

Product:

TTML 1.0

Description:

I see that the current spec does not indicate what timeline to use for
the purpose of interpreting time expressions in <flowIntervalFunction>,
namely, a <duration> argument to intra() or inter() flow interval functions;
it would seem appropriate that this should be defined to be the same
timeline as used for DFXP content, namely, as determined by ttp:timeBase; in
the case of SMPTE discontinuous (marker) mode, it probably should be real
time, since duration is not well defined on the discontinuous SMPTE
timeline; i will add normative text that calls out these timeline semantics;
