Yes, unfortunately it does. Extending element sets seems to be rather
tedious in the current XML tool set. Either you have the new elements
extend the old namespace, yielding the problem you mention, or each
new element (location type, here) gets a new namespace, yielding a
namespace list a mile long if there are lots of extensions.

Some additional comments on closer reading and a general comment:
This registry intentionally (if you look at the RPID document) is
not meant to directly extend the RPID schema. I suppose that one
could add that any location types added automatically become XML
elements in the urn:ietf:params:xml:ns:pidf:rpid namespace. I
don't know if that's appropriate.
Doesn't this make it hard/impossible to check if an RPID
document is schema-valid? (I mean keeping some element
names in a list that's not a schema.)
Perhaps that's not important for this application though.
