So, since the difference between IRIs and URIs is which characters
can be left unescaped, this would boil down to "don't use namespace
names with unnecessary escaping".  And because of the issue of case
in escapes, one might extend this to "don't use namespace names with
any escaped characters".  Does that seem reasonable?
