Great! I'm not completely crazy then (or at least I have company).

I'd like to hear more about it as well.

Cool. I did see some references to that flying past since I posted.

I don't suggest you create a new namespace for every rev.
Just one to identify the elements added by WHAT.
I assume that WHAT will try to avoid any conflicts with itself.

(and note that I'm not sure that WHAT's extended <input> element
should be in the XHTML ns or something else)

Exactly. The category and type of <output> is different from
elements in XHTML. It is also defined by someone else, and owned
by someone else. I don't think you should add elements into
a namespace that someone else defines.

This is another reason for strong branding around HTML 5.

No, I was saying that the W3C goofed up and regret the mistake.
That's partly why I suggest a new namespace.

If you don't make your own namespace, then you might as well 
have no namespaces. You have the root tag (<html>), what else
do you need? (I also think namespaces are not so friendly for
authors, but I'd like to see some way to know if my content is
W3C+WHAT HTML, W3C HTML or W3C+WHO HTML).

OK. My suggestion here was again more about branding. It seems
weird to have an HTML 5 and then an XML version that is XHTML with
WHAT-ext-mod. However, this is why XHTML is designed that way, so 
I'll accept it.

Why do they have to memorize a namespace for every element?
If their content uses <what:output> then all they need to
do is add xmlns:what on the root element.

I'm suggesting you prefix all your new HTML elements with "what:".
As Tim said, Microsoft have done this without problem in IE for 5 years.

Yeah, it's really ugly. That's why I suggest the alternative: WHAT
should clearly specify HTML 5 (or HTML WHAT) as well as an XML
version.  I think kludging into existing specifications is going to
confuse more people (more than the number of people hand-converting to
XHTML).

I really doubt it. They are going to have to put an XHTML ns
declaration in there anyway. I don't think this will be any harder
than fixing unbalanced content. Do you really think this is a bigger
complication?

Remember that hand converters are going to cut and paste a bit
of text (because no one can remember namespace URIs). Having
one or two NS declarations in that text isn't going to make
the task any harder.

Moving from HTML to XHTML isn't easy, and I really don't think much of
the existing web will ever move (in fact, I doubt much of the existing
web will change to anything -- be it to valid HTML, WHAT HTML or
XAML). What we can hopefully influence is new web content. If it
is produced by tools (eg blogger, typepad or MT), then it should be
possible to get it right most of the time.

That's great. Like I said, the main reason I ask is that I think
W3C should be able to use WHAT work if it proves useful.
