RE: i037: Replace QName's with anyURI

It rates fairly poor in the readability department, but is still IMO far
surpassed in opaqueness by the second example.  Since you chose a QName
for your example that is already pretty unreadable, this makes it clear
to me that even the worst QName gets uglier when mapped into a URI.
