this situation and thus it is safe to not change prefixes. The same
approach is used in Canonical XML:

As far as I am concerned what is in the attribute value is a name token. It
is only when it is used in another context, e.g. as the value of a match or
select pattern, that it becomes a qualified name. At this point you need to
be able to "expand" the prefix into a URI. My problem is that I need a way
of passing both the URI and the prefix to the transformed file, and I don't
want users to have to repeat the prefix n-hundred times.
