Actually, I don't think namespace-alias does introduce
any insanity (at least in the strict technical sense :-).
In the stylesheet, there are still two different namespace names
bound to two different prefixes. xsl:namespace-alias just
specifies an additional transform to be performed on output --
change the namespace name referenced by the stylesheet-prefix
to the one referenced by the result-prefix.
Identifying the namespace names by prefix instead of by URI
does violate the "no QNames-in-content" rule, sort of, but
none of the other Principles of Sanity.
