WCAG A11Y DPUB techniques

Hello DPUB Accessibility TF,

For the past few months we have gone through the WCAG Techniques looking to see what was relevant to DPUB.  Here is a summary of what we found so far.  We need to discuss the items that we feel are not required for DPUB and those we still had questions about so we can determine if they are relevant or not to DPUB.  Hopefully we can discuss these at our next meeting.  I will send out a reminder and hopefully a new time slot for this Friday if we can get the phone system switched over in time to host our call.

Here are the WCAG techniques and what we feel are relevant to DPUB.
