   * DIWG  : [2]

      + TM : [4] 
      + GA : [5]

Discussion of DIWG comments.

Resolution: For DIWG-1, agreed. Change transcoding to transformation.

Resolution: For DIWG-2, change "shall" to "should" in R109.

Resolution: For DIWG-3, we are making use of XSL-FO vocabulary for
its descriptive, authoring semantics, but there is no implication
that this vocabulary would or must be used in a distribution format.
A transformation process is capable of reducing these expressions to
CSS and other style formalisms in a distribution format.

Resolution: For DIWG-4, add statement in introduction stating that
all text is normative unless it is in note, an example, or is
otherwise explicitly indicated as informative.

Discussion of Nokia comments.

Resolution: General agreement to support NOK-1 but generalized as
described in GA response.

Resolution: For NOK-2, respond that this would be reasonable
requirement for a DF, but current work is on an AF. Invite Nokia to
participate in future on DF.

Resolution: For NOK-3 and NOK-4, AF != DF.

Resolution: For NOK-5, request clarification if they have some device
independent features for AF context.

Action: [GA] to package above comments for review by TTWG, then
send to commenters once accepted.

Action: [GA] incorporate agreed changes into TT-AF-1-0-REQ in
preparation for publishing final W3C Note.

************************************************************************
4. TT-AF-1-0 Specification Progress Review
************************************************************************

[GF] will send material he has to [TM] tommorrow. Most of work is
introductory, with examples for visual. No examples for aural style.

General discussion of aural parameters and SSML mapping.

Action: [SH] will review and propose subset of aural parameters
(see R305).

[GA] Can change "shall" to "should" in R305 if we have to.

[GA] Discusses meta data module. Indicates preference to have only one
meta element and not both meta and metadata. Three forms of meta could
be used:

1.  <meta name="foo" content="bar"/>
2.  <meta name="foo">bar</meta>
3a. <meta><m:mymeta xmlns:m="mymeta"/></meta>
3b. <meta name="mymeta"><m:mymeta xmlns:m="mymeta"/></meta>

[EH] On track for 15th for submission. It would help to know more
about body elements.

[GA] Suggest using what is thought best for time being. Editor will
integrate and unify.

[GA] On track for 15th for submission.

*** OPEN ACTION ITEMS ***

Action: [SH] Will investigate use of media queries in this context and
report back.

Action: [DS with help of Paul Nelson and Peter Lofting] Write RFC to
register appropriate opentype/truetype font types as MIME media types,
suggest model of "application/font-<font-type-name>", e.g.,
"application/font-truetype".

Action: [GA] Make proposal regarding use of Xlink vocabulary or
"src" attribute.

Action: [GF] Investigate whether to use IRIs instead of URIs?
Note: XPointer and Namespaces in 1.1 use IRIs?

Action: [SH] Investigate use of "role" vs "class" attribute.

Action: [GA] Investigate selection of non-TT vocabulary for
application of style/timing semantics.

Action: [GA] and [GF] Investigate mechanism for cascading
semantics and whether to support cascading on either or both
logical and presentation flowed vocabularies.

Action: [GF] Will send hotel info to [TM] within the next few days
for Feb F2F.

Action: [GA] to package above comments for review by TTWG, then
send to commenters once accepted.

Action: [GA] incorporate agreed changes into TT-AF-1-0-REQ in
preparation for publishing final W3C Note.

Action: [SH] will review and propose subset of aural parameters
(see R305).

*** OPEN ISSUES ***

Issue: Whether to use XLink vocabulary, e.g., as used consistently by
SVG, or use "src" attribute as apparently will be done in XHTML2?

Issue: Whether to use IRIs instead of URIs? Note: XPointer and
Namespaces in 1.1 use IRIs?

Issue: Should we use "class" instead of "role"?

Issue: Probably want to permit in logical content mode the selection of
content based on generic XML features of non-TT namespace descriptive
markup, e.g., for applying style and timing semantics, in which case an
appropriate TT container element shall be implied based on nearest
ancestor TT namespace element.

Issue: Need to think about cascading semantics; how to express, how to
apply, etc. Possibly use CSS semantics here as well.
