In article <OF495225A3.D1651174-ON85256AA3.005D15A5@com> you write:

Short answer: you can't. Slightly longer answer: you can hack it with
parameter entities - see the DTD for schemas for an example:

Yes, one of the reasons for schemas was to overcome this problem. You
declare a "target namespace" in the schema, and it validates instances
that use that namespace whatever prefix they use.
