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].
