Theory:

<snip href="http://www.w3.org/TR/xslt#xslt-namespace">
The XSLT namespace has the URI http://www.w3.org/1999/XSL/Transform.
. . .
XSLT processors must use the XML namespaces mechanism [XML Names] to
recognize elements and attributes from this namespace.
</snip>

The "theory" I was referring to was the Namespaces in XML Recommendation, not the XSLT Rec. By convention, the namespace "URI" generally follows the classic http://whatever URL form, but the purpose of the URI -- to disambiguate local names from multiple vocabularies -- could be served as well by using URNs (as Microsoft does to associate XML docs with a Schema, e.g.) or indeed by anything at all... "xyz," "MyDogHasFleas," whatever. There certainly doesn't have to be (as the expression goes) a "there" there at all.


In practice, as I said, the URI often has to have a specific value in order to signal to a processor (of whatever kind), "Hey, Processor, wake up! Elements using this (possibly null) prefix are for *your* attention!" And, as you said, a compliant XSLT processor uses the "http://www.w3.org/1999/XSL/Transform" URI as its wake-up call.

Okay, I'm being a butt. Time to go home. Good night.

Hmm. "Butt" is probably a little too harsh... but if I'd actually been reading the list at the time your message appeared, yes, I'd have told you to get some sleep. :)
