Editorial addition to the Techniques intro

 

As we get ready to republish the Techniques document, I’ve been looking
at the introduction. There is a typo to fix and I think we should add a
couple of  sentences  

  

There are examples in each technique which sometimes contain code snips
that are intended to demonstrate the principle discussed in the
description of the technique. The code is not intended to demonstrate
other aspects of accessibility, usability or best coding practises not
related to the technique.  

  

Here’s a shot at it in context with a couple of other edits which are
within 

   

Rather than having technology specific techniques in WCAG 2.0, the
guidelines and success criteria themselves have been written in a
technology neutral fashion. In order to provide guidance and examples for
meeting the guidelines using specific technologies (for example HTML) the
working group has identified __ for each Success Criterion that are
sufficient to meet that Success Criterion. The list of sufficient
techniques is maintained in the "Understanding WCAG 2.0" (and mirrored in
How to Meet WCAG 2.0). In this wayBy separating the WCAG 2 normative
guidelines document from the techniques used to meet the Success Criteria
in those guidelines it is possible to update the list as new techniques
are discovered, and as Web Technologies and Assistive Technologies
progress. 

Note that all techniques are . The "sufficient techniques" are considered
sufficient by the WCAG Working Group to meet the success criteria.
However, it is not necessary to use these particular techniques. If
techniques are used other than those listed by the Working Group, then
some other method for establishing the technique's ability to meet the
success criteria would be needed.  

There are examples in each technique which sometimes contain code snips
that are intended to demonstrate the principle discussed in the
description of the technique. The code is not intended to demonstrate
other aspects of accessibility, usability or best coding practises not
related to the technique. 

Most success criteria have multiple sufficient techniques listed. Any of
the listed sufficient techniques can be used to meet the Success
Criterion. There may be other techniques which are not documented by the
working group that could also meet the Success Criterion. As new
sufficient techniques are identified they will be added to the listing. 

In addition to the sufficient techniques, there are a number of __ that
can enhance accessibility, but did not qualify as sufficient techniques
because are not sufficient to meet the full requirements of the success
criteria, they are not testable, and/or are good and effective techniques
in some circumstances but not effective or helpful in others. These are
listed as advisory techniques and are right below the sufficient
techniques. Authors are encouraged to use these techniques wherever
appropriate to increase accessibility of their Web pages.
