Thanks. This is what I've been trying to say in the past few rounds, and I'll
admit (and have admitted) that I've been clumsy about it.

Is there a general problem with attributes having namespaces that would lead
to this BCP? I don't see it. Having implemented an XSLT processor, I can
tell you that it would have made little difference if unprefixed attributes in
xsl elements carried the XSL namespace.
