14:34:04 [nigel]
dsinger: I think combination content profiles inferred within a document is a mistake and we should only have the OR expression not the AND, i.e. those wishing to use an alternate profile should define it separately.
14:35:18 [nigel]
glenn: There are multiple uses of this, either externally in defining a profile and within a specific document for 'on the fly' processing.
14:35:30 [nigel]
dsinger: It's the second of those, the 'on the fly' that I think is a mistake.
14:36:04 [nigel]
glenn: We should think about that some more and think about if we want to make it asymmetrical, with respect to content profile combinations as opposed to processor profile combinations.
14:37:09 [nigel]
nigel: I believe the combination of profiles is described in issue-206.
14:37:16 [nigel]
glenn: I think david's raising a new issue
14:37:34 [Dsinger_]
Dsinger_ has joined #tt
14:37:53 [Dsinger_]
Issue-206
14:37:53 [trackbot]
Issue-206 -- Add ttp:profileCombination parameter -- pending review
14:37:53 [trackbot]
http://www.w3.org/AudioVideo/TT/tracker/issues/206
14:38:04 [nigel]
... It's that the complexity of supporting on the fly combination of content profiles is too complex and not needed.
14:40:05 [nigel]
glenn: I've added two editors notes, the second it in 5.2.4.2 that describes the content profile combination semantics
14:41:14 [nigel]
... If a receiving processor is able to do validation and it's required then it would use the content profiles otherwise there's no other use for content profiles. If we define validation processing well even in the context of content profiles then that leaves the judgement of complexity to the reader.
14:42:19 [nigel]
glenn: I would like to propose that we discuss profiles further at the upcoming F2F in September, and that I write some explanatory documentation, both in the spec and for the meeting.

14:49:17 [trackbot]

dsinger: mea culpa
14:50:45 [nigel]
nigel: an example for this may be extending or restricting permitted values e.g. for the tts:color attribute.
14:52:04 [nigel]
glenn: ttp:permitFeatureNarrowing and ttp:permitFeatureWidening are attributes that describe whether or not processors that implement narrower/wider versions to claim support.
14:52:50 [nigel]
... It's not predictable what the author wants so I added the attributes to cover those cases specifically.
14:54:11 [nigel]
nigel: Can we leave that open until there are some examples e.g. SDP-US color space.
