================================
Response from the Working Group
================================
One of the requirements of WCAG <http://www.w3.org/TR/wcag2-req/> is
to ensure that requirements may be applied across technologies and to
ensure that the revision is "backwards and forward compatible". We
agree that this makes the language of the guidelines more abstract and
we have provided the Understanding and Techniques documents to help
authors better understand how to apply the guidelines when using
different technologies.

Note that because the Understanding and Techniques documents are not
normative, it possible for the working group to add to and revise them
without going back through the W3C Recommendation process. This will,
for example, make it possible for us to include HTML5 techniques when
it becomes a recommendation.

How to Meet WCAG 2.0 <http://www.w3.org/WAI/WCAG20/quickref/> already
addresses part of this concern as it can be configured to show only
the techniques in the technologies of interest.

We hope that once WCAG 2.0 has become a Recommendation and is stable,
additional document and resources will be created that will make it
easier for authors who are only interested in specific technologies.
