As further clarification to the decision support proposal.

Techniques to meet this success criteria would include any support 
that answers questions such as:
- what are the accessibility implications of making this choice?
- what will i need to do to make this 
technology/markup/element/component accessible?
- what accessibility support does this 
technology/markup/element/component provide?

In a Web App development toolkit this may be met by an indication of 
which components or component sets offered include ARIA markup.
In a generic Web content development tool this may be met by 
indicating how captions can be included in Flash vs. Quicktime vs. 
Real etc.
In a Wiki editing tool this may be met by indicating that the html 
based styling mechanisms are more accessible.

These advisories can be offered in the form of unobtrusive icons with 
links to further information or a dialog or in other ways appropriate 
to the look and feel of the interface.
