Well stronger than that, If you change the namespace you have changed
the name of every token in the language so it's not a new version it's a
new language. Sometimes that's what you want to do SGML->XML dsssl to
xslt etc but if the language is plausibly a new _version_ of an existing
language it ought to have the same namespace (a policy that isn't always
followed:-)
