Well, an XSLT document with no XSLT-namespace elements isn't really an
XSLT document: ``XSLT processors must use the XML namespaces mechanism
to recognize elements and attributes from this namespace''.  Yes, if it
removed non-XSLT-namespace _attributes_ it wouldn't be much use, but
that whole business works because XSLT processors are more-or-less
required to use Simon's best-practice recommendation, and take
unprefixed attributes in XSLT elements to be also in that namespace.

Also yes, this isn't the only way to use namespaces.  But I think that
`what document do we get after a namespace transformation' is a pretty
clear way to think about them, where some problems just evaporate.

I'm with you.  I don't find it a major complication, but section 5.2
would most agreeably disappear if default namespaces didn't exist,
which may or may not be desirable....

Badly expressed -- I only meant that the concept `global attribute'
doesn't seem at all valuable, and appears to only confuse things.

All the best,

Norman
