Dear Wendy,

Thanks for your comments on the Last Call version of the QA Framework:
Specification Guidelines[0] - 22 November 2004

After two weeks from now (on May 18, 2005), the lack of answer will  
be considered as if you had accepted the comment.

Original Comment (Issue 1082 [1]):

As a response to your comment, the QA Working Group has accepted
your comment.  The QA Working Group indicates that the WAI CG's
  interpretation as stated in the Original Comment is correct and that
  WCAG2.0 guidelines/success criteria can be extended, because the
  Guidelines are deliberately generic; thus they can be applied and
  adapted (extended) by different policy makers, and extensibility
  is appropriate. The QA Working Group suggests that WCAG2.0
  documentation indicate that it is allowable to add additional
guidelines/criteria to those already in WCAG2.0 for the
previously-stated purpose, but that such additions should be in
  the style of existing WCAG2.0 success criteria/guidelines if
  possible. Furthermore, the QA Working Group suggests that the
  mechanism for such extensibility should be defined formally
in the WCAG2.0 documentation. The QA Working Group believes
that such extensibility considerations as mentioned previously
  are consistent with 2.4.3 Extensibility and Extensions in the
  revised SpecGL draft [2].
