That's *one* way to use namespaces, yes.  A view of an XSLT document
that removed all but XSLT-namespace elements would be pretty useless;
still less a view that removed only the XSLT-namespace elements.

So it is, and AF's a good thing, but not the only thing.

Bah.  The default namespace is a mere syntactic minimization; it allows
us to pick any one prefix and eliminate it from the syntax.  At the
Infoset level, prefixes are supplied because of the possible presence
of QNames in character data, but they aren't *meaningful*.

Consider XLink: it happens to fit perfectly into your view, using
nothing but global attributes.
