This is the sticky bit.  Tim Bray phrases it as "If necessary, rewrite
the DTD so that the same URIs have the same prefixes in DTD and

However, there is no formal way to express what prefixes in the DTD
refer to what namespace URIs.  In essence, you must know that in
advance.  For validation to be a mechanical process, you must have
some way of recording the frozen namespace-URI map for the DTD.

(Please don't mutter "PI".  That is what the old draft had, and a good
thing it was too, but the new draft abandoned it.)
