ISSUE-284?

<trackbot> ISSUE-284 -- value of lineHeight -- raised

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/284

sean: this is mostly related to ttml2 which is now being prescriptive instead of a recommendation
... we could make this (the percentage) a rec in ttml2 as well, so there would be no conformance issue

<Dsinger> It maps to a specific value on each platform, but maybe not the same value...

<scribe> ACTION: glenn to change to rec in ttml2, and add note to authors indicating that if author wants specific value, then they should specify specific value [recorded in http://www.w3.org/2013/10/17-tt-minutes.html#action01]

<trackbot> Created ACTION-219 - Change to rec in ttml2, and add note to authors indicating that if author wants specific value, then they should specify specific value [on Glenn Adams - due 2013-10-24].

http://lists.w3.org/Archives/Public/public-tt/2013Oct/0010.html

glenn: the above shows that the max height of all lines applies to the entire para

<scribe> ACTION: pal to investigate actual CSS behavior further regarding whether line height of individual lines are affected by font size on line as opposed to maximum over paragraph [recorded in http://www.w3.org/2013/10/17-tt-minutes.html#action02]

<trackbot> Created ACTION-220 - Investigate actual css behavior further regarding whether line height of individual lines are affected by font size on line as opposed to maximum over paragraph [on Pierre-Anthony Lemieux - due 2013-10-24].

<scribe> ACTION: glenn to double check spec language on CSS and XSL-FO around line height stacking strategy [recorded in http://www.w3.org/2013/10/17-tt-minutes.html#action03]

<trackbot> Created ACTION-221 - Double check spec language on css and xsl-fo around line height stacking strategy [on Glenn Adams - due 2013-10-24].

<trackbot> ISSUE-283 -- Deterministic text wrapping and presentation -- open

<pal> Under "Liaisons with W3C Groups", I would add the Web&TV IG

sean: must is a stretch for described video

dsinger: under deliverable 2, if "previously specified" then already in spec text

<plh> remove "previously specified but now"

plh: can say "previously unspecified features"

<plh> fix "Text Text"

dsinger: should say something about CSS as a mapping

plh: already have this via "mapping" activity

<plh> move item 6 into item 1 (TTML 2)

dsinger: surprised that 608/708 aren't mentioned under deliverables

mike: notes that SMPTE TT has done this
... nothing wrong with mentioning this in charter

dsinger: can be mentioned as to be considered as opposed to new deliverable
