Okay, we agree.

It can be. It can also be a feature of the document type. i.e. sometimes
you are doing "CONCUR" and sometimes you are doing "subtyping". I
consider it a flaw that architectural forms conflate the two concepts.

I didn't require that *in general*. I said that *for HTML* it is not
appropriate to require extra attributes in the document. They are as
intrusive as the xlink: prefixes I am trying to get rid of.

I am not a big fan of this "feature" but even if I did think it was
wonderful for some situations and document types, it is not appropriate
for the problem of removing extraneous markup from XHTML.

I disagree. As long as there is any other information in the document
establishing a globally unique name (e.g. a DTD declaration or namespace
declaration) I can use that as a key to invoke my XLink recognition
process. If I cannot depend on my processor to "know" how to find an
XLink recognition document based on my namespace, then I can have a
magic attribute as W3C XML Schema does.
