There is a down side to this approach (see below)

If you want to be fatalistic about it, it seems that no matter what you
do, some tools will find some way to generate "yucky" markup, and will
be "collosally bad at consuming them".


Sorry, I can't resist; but realistically you have to deal with the fact
that once OpenID starts to appeal to the template hackers, other tools
will likely prioritize conformance to OpenID specs in much the same way
that LiveJournal has prioritized conformance to syndication specs.

Frankly, he truth is that from a cut and paste point of view, I don't
think it much matters whether the rel value is 15 characters or 50.  But
from a spec point of view, html link rel values are meant to be case
insensitive, something that will pose interoperability issues with URIs...

And on a related note, while I heard a few murmurs of approval on my
attempts to validate yadis xrd documents, I didn't get much constructive
feedback (in terms people identifying documents that are valid but
flagged, or things that would be helpful to flag).  If still looks to me
like a barn door that people will become interested in closing once the
cow escapes.
