RE: TT telecon - agenda for 12 Dec

I've just been looking at the SVG specification and the section on
extensibility... (Section 23)
I do like the fact that SVG allows extensions, but I'm not personally
convinced it gives what I need. 

[I would support inclusion of Foreign namespaces and private data in
DFXP. (23.1)]
[I don't think that supporting foreignObjects ( or Adding private
elements and attributes to the DTD is necessary. (23.2 - 23.5)]

Certainly the requiresExtension attribute does not match what I had in
mind :-)

With apologies to those that read (and write) fluent xml... 
What I'm thinking about is something along the lines of a
requiredTransformation attribute on the tt element...

<?xml version="1.0" encoding="utf-8"?>
<tt xml:lang="en"
    xmlns="http://www.w3.org/2006/10/ttaf1"
    xmlns:tts="http://www.w3.org/2006/10/ttaf1#style"
    xmlns:ttm="http://www.w3.org/2006/10/ttaf1#metadata"
    requiredTransformation = "x-SSS_DFXPtoTeletext>

  <head....
  </head>

  <body ....
  </body>
</tt>


For CCforFlash - all that I can see that would be necessary to be
conformant and allow the current CCforFlash behaviour would be ...

<?xml version="1.0" encoding="UTF-8"?>
<tt xml:lang="en" xmlns="http://www.w3.org/2006/04/ttaf1"
xmlns:tts="http://www.w3.org/2006/04/ttaf1#styling"
    requiredTransformation = "x-DFXPCCForFlash>
  <head>
        <styling>
            <style id="b1" tts:color="#cccc00"/>
       </styling>
  </head>
 
  <body>
    <div xml:lang="en" style="b1">
            <p begin="00:01.7" end="00:05.0">Narrator:  Someone watching
a car<br/>accelerate toward light speed</p>
...
   </div>
    <div xml:lang="es" style="b1">
            <p begin="00:01.7" end="00:05.0">Narrador:  Si se observara
a un auto<br/>acelerando a la velocidad de la luz</p>
...
    </div>
    <div xml:lang="de" style="b1">
            <p begin="00:01.7" end="00:03.4">Sprecher:<br/>Wer ein Auto
beobachtet</p>
...
    </div>
  </body>
</tt>

Absence of a requiredTransformation attribute would of course imply the
behaviour defined by the specification,

Subject: TT telecon - agenda for 12 Dec


Here is an agenda for today. Basically this is finishing the agenda from
last week.
We need to make a decision on dynamicFlow, so that is the first topic

I've also included a section to record the other issues that have arisen
this week, but don't expect we shall get to all of them.

This is the last WG meeting till the new year, but that doesn't mean no
TT work, we will be compiling a survey of all the outstanding issues,
which will be open until Jan 5. I'll then collate the results and we
will discuss them on our next scheduled meeting on Jan 9.

Agenda

1) dynamicFlow

2) timeContainer and default value for <body>

3) extent to move (back) to tt element?

4) qualify 9.3.2 (7) to map anonymous spans to fo:inline only when their
parent is p or span

5) dealing with inherit for anonymous spans:
"For the purpose of determining applicability of this style property,
each character child of a p element is considered to be enclosed in an
anonymous span where the value of this style property is set to
'inherit'".

6) Adopting a smaller set of the real number line for opacity.
<simpleType name='alpha'>
  <restriction base='decimal'>
    <totalDigits value='4'/>
    <fractionDigits value='3'/>
    <minInclusive value='0'/>
    <maxInclusive value='1'/>
  </restriction>
</simpleType>

7) Enhancing presentation of computed style set for content elements

8) Marking additional processing requirements with a requiredExtensions
attribute.

9) supporting tts:display on region

10) modifying lineHeight to accommodate nested spans

11) tts:padding

12) Content Hierarchy Region Mapping example code typo

13) region attribute not specified and default region

14) disallowing style as a child of region

xx) AOB
