Yes, please. May be W3C has same plan how to assign version numbers to
different language that want to be named XHTML x.y. But if there is no
such plan I think that our WG should work together with XHTML2 WG to
agree on naming rules.

I think that using different name than XHTML will be confusing because
relation between XHTML1.0 and XHTML5 is very similar to relation between
HTML4.01 and HTML5.

At the same time it will be confusing to use XHTML5 when XHTML2 will
break evolution path:

XHTML1.0/1.1 is in http://www.w3.org/1999/xhtml namespace

XHTML2 is currently in http://www.w3.org/2002/06/xhtml2/ namespace and
it is not backward compatible with XHTML1.0/1.1

XHTML5 is in http://www.w3.org/1999/xhtml namespace and it is more or
less compatible with XHTML1.0/1.1

In this case it seems more logical to use XHTML1.5 instead of XHTML5.
Numbering scheme could be very simple: XML serialization of HTMLx.y
(where x >= 5) will be named XHTML1.x.y. Yes the version numbers are not
completely same, this is not ideal. But web developers are used to this
as XHTML1.0 corresponded to HTML4.01.

Standardization work is consensus building. I don't see how consensus is
built by flooding Google indexes by term which one group of people prefers.

Yes, if XHTML2 WG will stop using "XHTML" label for their language, then
I don't see any problem in using XHTML5 and it will be the best option
then. But are they willing to do it? If not and if HTML and XHTML2 WG
couldn't find agreement on naming scheme who will resolve it?

Anyway, whether it will be named "XHTML5", "XHTML1.5", "HTML5/XML" or
whatever, it is just label, no reason for argument. I just feel little
bit strange of using XHTML5 without approval from XHTML WG and then
saying, hey Google knows zillions pages about XHTML5 so we will use this
name anyway.
