"names of resources and names of locations of resources" - even
conflated - concern things which are independant of the one, single
property intrinsic to namespaces: the capacity to disambiguating names.
which, i would trust, remains part of the "core". establishing identity
with respect to
<asdf xmlns='12345' />
<abcd:asdf xmlns:abcd='12345' />
is no different than doing so with respect to
<!ENTITY % qwer 'asdf'>
<!ELEMENT %qwer; EMPTY >
none of which has to do with either the names of resources or the names
of locations of resources.

which has nothing to do with the identity of the names in the respective namespace.
