Hi Gregg,

Thank you very much for these updates. Some comments inline below:

For example, how about something like "The Role of Techniques and Failures in WCAG 2" rather than "Proper Use of WCAG 2.0 Techniques and Failures"? I think we need to find the balance between explaining what techniques and failures are, and cautioning potential misuse due to misunderstanding of their intended purpose.

(not negative - but short and focused on clarifying rather than instructing.      "The Role of...."   is all in the Understanding document.    We were asked for something VERY SHORT and VERY CLEAR  that could be used by people who misunderstood the Role.    I am concerned that adding more words -- or turning this into a general discussion -- would defeat what we were asked for.

Currently WCAG-EM is intended to instruct _evaluators_ (as opposed to 
authors/developers) on how to use techniques and failures (not only 
those from WCAG WG) throughout a conformance evaluation process. It 
references existing guidance in Understanding WCAG 2.0 and in WCAG 2.0 
itself, but Eval TF also previously reported back that this guidance may 
be too sparse. For example, there is currently no description of what 
"failures" really are. We tried to provide such guidance here:
  - http://www.w3.org/WAI/ER/conformance/ED-methodology-20130208#step1d
  - http://www.w3.org/WAI/ER/conformance/ED-methodology-20130208#step4c

We received an objection on these two sections in the WCAG WG survey:
  - https://www.w3.org/2002/09/wbs/35422/WCAGevalTaskForce/results#xprocedur

It seems that these comments are more of policy guidance nature and 
additional to the technical guidance that we are trying to provide in 
WCAG-EM. It is an issue that is beyond the scope of WCAG-EM alone. I 
don't think we can fully replace the guidance we currently provide in 
WCAG-EM with this new text on proper use of techniques and failures.

Given the breadth of this issue I think we now need to decide if we need 
to hold publication of this updated Working Draft of WCAG-EM, or if we 
can maybe add some reviewer notes into the document clarifying that we 
expect these two sections to be updated in future drafts. It would allow 
WCAG WG to update its guidance on techniques and failures while Eval TF 
focuses on further refining WCAG-EM in parallel.

If we can work in parallel, what reviewer notes and/or immediate fixes 
would you suggest for the current WCAG-EM sections (step 1.d and 4.c)?
