Ok, so you are proposing a comment that will always remain in the DOM.

What's the use case? (That's partly rhetorical; see below.)

If you want the content ignored, why are you putting it in the document?


The point is that you _don't_ want it to be ignored. You want it to be
ignored on WF2 UAs, and not in legacy UAs.

So effectively it's a "conditional comment", except that the condition is
"supports the <ignore> element" (or attribute, whichever).

It is basically equivalent to <legacy value="Web Forms 2.0">. See:
