That's why I wanted it. :^) The aim is to make those extensible
enumerations where people can add their own elements but must do so in a
way that won't tread on where we might wish to put our toes in future.
The other sensible way of doing this is the informal technique used in
specifications like CIM, where you just have a common prefix to all the
values that you define. But if you're doing that, you might as well
formalize it in terms of common XML rules.

In terms of parsing, I think both SAX and DOM have support for making
this sort of processing easy...?
