RE: Processor Conformance

Chris,

Thanks for your comment. The TT WG has reviewed this comment has agreed
upon the following response:

The intention is that the presentation processing defined by DFXP that
extends beyond or differs from XSL 1.0 also be required by a conformant
presentation processor. That is, a strictly XSL 1.0 conformant formatter
would not be wholly adequate. The text will be clarified to make this
intention more clear.

Regards,
Glenn

Subject: Processor Conformance


Hello public-tt,

section 3.2 Processor Conformance states:

  If the processor claims to support presentation processing in order to
  produce a rendition of TT AF content on a visual medium, then it must
  implement the region and line layout semantics defined by 9.3 Region
  Layout and Presentation and 9.4 Line Layout, respectively. In
  addition, the processor should satisfy the user agent accessibility
  guidelines specified by [UAAG].

section 9.3.2 Synchronic Flow Processing states:

  for each TT AF style property attribute in some computed style
  specification set that has no counterpart in [XSL 1.0], map that
  attribute directly through to the relevant formatting object produced
  by the input TT AF content element to which the style property
  applies;

My question - it is not clear whether an XSL-FO processor which claims
to be a TTAF- DFXP processor and claims to support presentation
processing, but does not support any TT AF style properties that are
not already in XSL 1.0, is a Conformant Processor per 3.2.

Please clarify. If it would be conformant, are the extra TT AF style
properties ignored?
