Re: Namespace name: better to use URN or URL?

Yes, but a namespace name is essentially the name of a vocabulary, and
something that you might expect users of that vocabulary to have to
write. On a good day I can remember the MathML and XSLT namespaces off
the top of my head, I doubt whether I'd ever remember a uuid based name.

Names based on the domain name system (http:// or mailto: etc) do have
the good properties of being relatively easy to generate (relatively)
uniquely and be memorable. They have the bad property of tempting the
designers of XML Schema to suggest that a schema validator might try to
use the URI for something which famously "is not a goal" of XML
Namespaces, but that's the price you pay, apparently.
