I disagree (with the proposal). TTML2 should not incorporate non-TTML namespace vocabulary. Further, there is no requirement that TTML2 be a syntactic superset of industry profiles.
I believe we agreed at today's F2F that we would not add ebutts:linePadding to TTML2. Is this correct? If so, then could the reporter close this?
ebutts:linePadding
as specified in EBU-TT-D and referenced by IMSC 1.0.1 has been adopted by the industry.TTML2 provides similar capabilities by adding support for padding on span (see https://www.w3.org/TR/ttml2/#style-attribute-padding). This approach however has a number of drawbacks:
ebutts:linePadding
, complicating the life of users and implementers alike, without improved CSS support (since CSS does not support the proposed TTML2 syntax)ebutts:linePadding
(since each span can have a different value) without having demonstrated why such complexity is needed for subtitles/captions (or timed text in general)The
ebutts:linePadding
vocabulary and syntax should be added to TTML2.
