Would a test for mismatched or undefined namespaces be necessary?

For example:

Mismatched namespace:
<pg:foo xmlns:pg="http://postgresql.org/stuff">bar</my:foo>

Undefined namespace when used in conjunction with IS DOCUMENT:
<pg:foo xmlns:my="http://postgresql.org/stuff">bar</pg:foo>

Also, having a look at the following example from the patch:
SELECT xml_is_well_formed('<local:data
xmlns:local="http://127.0.0.1";><local:piece id="1">number
one</local:piece><local:piece id="2" /></local:data>');
 xml_is_well_formed
--------------------
 t
(1 row)

Just wondering about that semi-colon after the namespace definition.
