I am just curious to know why you want to eliminate the possibility to
change the namespace URI if there were a really major change in the XML
vocabulary.

You can always state that the URI may change in a future "major release"
and keep the possibility to consider that all your changes are consider
as "minor" in the life cycle of your vocabulary (it's a matter of "may"
vs "must"...).

You have 2 possibilities for versioning and I think that the safest
positition is to keep both :-)
