Perhaps I just didn't make myself clear :-)

Well, I don't know what the XHTML folk are planning, but it doesn't really
matter. If you just what XHTML regardless of version or strictness, you
would just say
In other words, with prefix matching, you don't need to match exactly at a
directory separator "/".

I liked it too, but this may change in light of the current XHTML namespace

You can still do prefix matching if they consistently use

Probably, in as much as it keeps them free from their TR URL scheme, but, as
I note above, if one is just doing prefix matching, the "/" separator isn't
necessary (although I agree with you that it is neater to have).

As I noted in an earlier post, any (single) hierarchical representation of a
set of features forces you to prioritize axes (ie pick one permutation). If
You could specify for version and underspecify for strictness, but *not* the
other way around.
