Hi Alistair,

The techniques are already organized by HTML element, like the HTML spec. If you want to find out about authoring data tables then you go to the data tables section. Example:
http://www.w3.org/WAI/GL/WCAG20/WD-WCAG20-HTML-TECHS/#datatables

The test suite is organized by HTML element as well. Is this the "applicability condition" you need?

Cheers,
Chris

  Subject: Applicability Conditions For Techniques


  Dear All, 

   

  I believe there is a need for each technique to contain one or more simple statements which define the conditions under which the technique is deemed applicable - an example of such a statement might be simply 'This technique is applicable if one or more data-tables have been used'.

   

  The benefit of doing this is that it allows a user to determine without doubt whether or not a technique is relevant to their situation - if it is applicable they can proceed to test whether it is 'passed' or 'failed', and if it isn't they can mark it as 'non-applicable'. 

   

  By providing 'applicability conditions' I believe it further strengthens the 'testability' of the guidelines.  This extra step ensures that decisions as to 'applicability' can be made with certainty, providing an almost prescriptive framework (taking into account 'testable statements') by which a technique can being declared as 'passed', 'failed' or 'non-applicable'.  

   

  Please let me know your thoughts.
