So *anything* that appears in documents is in scope? That's news to me.

I recommend you look at the two RFCs, then you'll realize this refers to 
a different topic. The VCARD extensibility mechanism is defined in

You brought up "no normative status whatsoever". I just pointed out that 
this is temporary, and also applies to HTML5.

So once new VCARD elements get defined, how will they be added to HTML5?

So *will* you fix it once draft-ietf-vcarddav-vcardrev is approved for

You're abusing your editorial power to include things into HTML5 that 
you happen to be interested with.

The proposal is *not* to make it part of the language. (And, btw, I've 
seen several other people agreeing with that, favoring a more generic 
approach instead).

BTW, I notice that you didn't reply to:

Some of which being more important, and related to *existing* interop 
problems of UAs, btw.
