Thank you for the history and context of the feature.

And yes, while I'm a standards advocate in my spare time, I do work in 
the commercial industry and it's very rare that we make flat/static 
XHTML files that stay static. If we do, it is so they can get shipped to 
a third party that will chop it up to be integrated in a CMS or 
templating system, and generally, it does not guarantee a nice valid 
document at the end regardless of what effort we made to create valid

This is very useful for developers without a full understanding of good 
markup habits, and were simply told "to do it".

I think this is very fair and a good disclaimer :)

The "tabs" are, but the "options link" which will go away(?) is not at 
the moment.

Fortunately, or unfortunately, I have very good eyesight for colours, so 
  I'm not always able to spot the contrast problems myself.

A very useful tool is a Firefox extension from JuicyStudio:

I sincerely hope this makes the release.

Thank you all for the discussion and your time. Your work is very much
