   sean: is LC for May for 2nd Ed reasonable?
   ... if any new features, will need LC; otherwise, may not need
   LC
   ... thinks there will not be new features, i.e., substantive
   changes

   <scribe> ... new features will be in TTML.next

   glenn: agrees that substantive changes probably not required

   -Regrets: miked

   sean: only concerns are with SMPTE timing and profile changes
   ... however, consensus is that LC probably not needed
   ... will continue with May timing

Review of Issues

   ISSUE-165?

   <trackbot> ISSUE-165 -- allowing set to animate more than one
   attribute. -- open

   <trackbot>
   [17]http://www.w3.org/AudioVideo/TT/tracker/issues/165

     [17] http://www.w3.org/AudioVideo/TT/tracker/issues/165

   sean: in trying to simulate pop-on style, would like to
   simplify by specifying multiple attributes in a single set
   element
   ... or could have set reference a style element in order to
   animate entire style set referenced through style element

   glenn: this would be TTML.next

   sean: yes

   ISSUE-151?

   <trackbot> ISSUE-151 -- Clarify syncbase in SMPTE continuous
   mode -- open

   <trackbot>
   [18]http://www.w3.org/AudioVideo/TT/tracker/issues/151

     [18] http://www.w3.org/AudioVideo/TT/tracker/issues/151

   <Sean> hello?

   sean: was smpte mode intended to be marker based for both
   continuous and discountinuous cases?

   glenn: yes, smpte timebase was intended to be marker mode
   irrespective of value of ttp:markerMode value

   sean: if intent was that smpte/continuous is intended to be
   marker mode, then we need to clarify spec; if not, then we need
   to remove
   ... suggests that glenn closely read the current spec text,
   then writes a CP to address this issue
   ... will need to deal with the problem that (informative) notes
   in 6.2.6 (ttp:markerMode) seem to be specifying normative
   semantics that should be present in normative text

   ACTION glenn to review and draft CP for resolving ISSUE-151

   <trackbot> Created ACTION-51 - Review and draft CP for
   resolving ISSUE-151 [on Glenn Adams - due 2012-03-29].

   ISSUE-154?

   <trackbot> ISSUE-154 -- Clarify the endsync behavior -- open

   <trackbot>
   [19]http://www.w3.org/AudioVideo/TT/tracker/issues/154

     [19] http://www.w3.org/AudioVideo/TT/tracker/issues/154

   sean: simpler than 151, but still may need change to spec
   ... problem is that we don't specify endsync, which has a
   default of 'last'
   ... for most part this works, but may not work in marker mode
   ... problem is that parent needs to stay alive until children
   see their end markers
   ... could fix by changing default for endsync behavior to 'all'
   ... in fact this default could be applied throughout
   ... proposes introducing semantics that endsync behavior is
   'all', at least for marker mode, but maybe for all modes
   ... will write CP to this effect

   ACTION sean to draft CP for resolving ISSUE-154

   <trackbot> Created ACTION-52 - Draft CP for resolving ISSUE-154
   [on Sean Hayes - due 2012-03-29].

   ISSUE-162?

   <trackbot> ISSUE-162 -- profile discrepancy -- open

   <trackbot>
   [20]http://www.w3.org/AudioVideo/TT/tracker/issues/162

     [20] http://www.w3.org/AudioVideo/TT/tracker/issues/162

   mike: does profile specify a document profile or a processing
   profile?

   sean: believes it is fairly clear in spec

   mike: industry is not clear on this, so perhaps needs more
   explicit language to this effect

   sean: ... perhaps we should (could) add new mechanisms to
   support specifying document profile, but suggest this be
   TTML.next action

   mike: most important that intent is clear

   sean: would be reasonable to add more clarifying
   text/examples/etc.

   ACTION glenn to address or draft CP to resolve ISSUE-156

   <trackbot> Created ACTION-53 - Address or draft CP to resolve
   ISSUE-156 [on Glenn Adams - due 2012-03-29].

   sean: any action to create new document profile should be
   introduced with a new issue
   ... what happens if profile refers to a feature we don't
   define?
   ... when we introduce new feature designators in future, then
   what is processor behavior for older processors?

   glenn:
   [21]http://dvcs.w3.org/hg/ttml/raw-file/tip/ttml10/spec/ttaf1-d
   fxp.html#conformance-generic-processor

     [21] http://dvcs.w3.org/hg/ttml/raw-file/tip/ttml10/spec/ttaf1-dfxp.html#conformance-generic-processor

   see item (3)

   mike: if no profile is specified, then processor should not
   reject (for that reason)
   ... in other words, should be optional

   ACTION glenn to clarify behavior regarding processor behavior
   when encountering feature for which no used or required is
   indicated

   <trackbot> Created ACTION-54 - Clarify behavior regarding
   processor behavior when encountering feature for which no used
   or required is indicated [on Glenn Adams - due 2012-03-29].

Adjournment

   adjourned

   trackbot, end meeting
