Re: Recommendation to move WCAG Techniques out of TR, concerned about Failure Techniques loosing authority

I would like to state unambiguously: I am greatly in favour of a publishing/editing process that makes it easier to fix bugs in techniques and to update/improve techniques in a timely manner.

If a company or country wants to specify that you need to require use of the non-normative techniques in their own rules we can advise against this (and we have) but have no means to stop them.  No means to stop them doesn’t mean that we need to change what we do though to compensate for their decisions.

In fact, Failure F8 (http://www.w3.org/TR/WCAG20-TECHS/F8.html) could be referenced to indicate that the third video fails the SC which makes the page fail.

One issue in a page and you have a failure.  One bit of success on a page and you merely haven’t yet failed.  I’d say that this doesn’t make failures any “stronger” than techniques, just that they have a lower bar to clear to be considered applicable.

If there are legal implications to hosting techniques in non-TR space I have no idea what they might be, and as we’ve advised expressly against such things, I don’t think that we need to concern ourselves too much with that.  We will still have a process for reviewing draft techniques and a way to indicate that techniques are published, and all of that process will be documented and transparent.
