RFC3023 and diff "If supplied, the charset parameter must match the XML encoding declaration." plh: Remove all references. mike: Detailed reply by Mike. ... Talk about this sentence. [8]http://lists.w3.org/Archives/Public/public-tt/2012Nov/0036.h tml [8] http://lists.w3.org/Archives/Public/public-tt/2012Nov/0036.html If supplied, the charset parameter must match the XML encoding declaration, or if absent, the actual encoding scribe: Filed a new Issue-197 on TTML 1.0. ... If supplied, the charset parameter must match the XML encoding declaration, or if absent, the actual encoding. plh: Check XML spec. mike: Silent. plh: UTF-8 or 16 or you have to have a XML declaration. mike: Even if only UTF-8 or 16, you still have issues. plh: What is actual encoding definition? mike: TTML 1.0 is silent. XML 1.0 is unclear. [9]http://www.w3.org/TR/REC-xml/#charencoding [9] http://www.w3.org/TR/REC-xml/#charencoding [[ parsed entities which are stored in an encoding other than UTF-8 or UTF-16 MUST begin with a text declaration (see 4.3.1 The Text Declaration) containing an encoding declaration ]] glenn: Discusses what XML 1.0 says. sean: TTML doesn't specify this. Is it premature to register a MIME type at this time. ... If we tackle all the issues for XML, we need to have a note on application of TTML using XML encoding. glenn: Could have a TTML 1.0 SE appendix that defines a wire encoding. [discuss optioins] c/options plh: ttml+xml mike: We are left with the specification telling us to do something without a MIME type.

[Discuss what we do in testing.] mike: Let lapse. We can start over. sean: Lapse and get ducks in a row with a new note and then re-register. glenn: Still wish to put an annex in SE. sean: Complete by next week's call. Action Glenn Create an Annex on using of XML wire encoding in TTML 1.0 SE. Created ACTION-132 - Create an Annex on using of XML wire encoding in TTML 1.0 SE. [on Glenn Adams - due 2012-12-06]. plh: Respond to IANA we won't be ready by Dec 15. mike: We have most of the bits to redo a submisson that is acceptable to IANA. Resolution: Agreed to give Glenn 1 week to write an Annex. If this doesn't materialize, send email to IANA on the expiration of the request. SDP-US Issues and Actions Issue-182?

[TTML10] allows zero or more profiles (ttp:profile in the head element) to be specified and used simultaneously. A presentation processor may reject documents it does not understand. sean: Close on SE on Issue-183. glenn: TTML 1.0 talks about semantically additive profiles. sean: Algorithm exists. glenn: Agreed. sean: Have implemented TTML 1.0 and it gave me an answer using the algorithm. ... May need more text to describe. mike: Agreed it should be in TTML 1.0. ... DXFP 1.0 + SDP-US profile is the issue. ... Deal with in TTML 1.0. glenn: How does ttp:profile constrain processor or content. Issue-190?
