For the record (without rehashing the many past comments on this issue),
Sun Microsystems opposes creation of a new text/xhtml Internet Media Type
as a mistake.  The web doesn't need a new media type for each markup 
language, the W3C needs to create a generalized solution for XML. The 
text/shoeml argument, reductio ad absurdum.

I believe we need to further coordinate with existing content negotiation
efforts in a suitable solution. I thought we'd begun progress on this
issue, but I've seen nothing posted to the WG mailing list on the topic.
Has the XML CG not provided any comments? Has there not been any discussion?

And yet any occurrence of an element of blockquote, table, etc. is the
same regardless of DTD. You are conflating namespaces with DTDs, which
are different animals. We consider all three DTDs to be "XHTML", and
semantically, that is the namespace.

I am not opposed to this (and have stated so both publicly and privately
to Paul Grosso, who provided the spur of this argument), so long as the
W3C makes a policy decision to actually provide such a service, makes
this decision publicly, and provides this WG with three suitable URIs
for the DTD. Until such time, we'd be guessing the URIs, and we'd
also be assuming that they were canonical. This would be a mistaken
assumption without the W3C making this official.

I agree with this, and certainly of the rest of Shane's editorial remarks.
I think removing the spaces from " />" in the examples (as suggested by
Shane) would satisfy the last call comment by Bill Smith regarding the
space not being normative.
