================================
Response from the Working Group
================================
You are correct that failure to use one of the WCAG 2.0 Sufficient
Techniques is not necessarily a failure of the success criterion. G1 and
G124 are written to position the links as the first links on the page
because the working group feels that is best practice, and to be
encouraged. However, as long as there is some mechanism to skip blocks of
repeated material, the success criterion has been met.
