Not infrequently, the scope established by the instance requires one to change
an attribute declaration from something like:

   <!ATTLIST foo   id    ID   #REQUIRED>

to

   <!ATTLIST foo   id    CDATA   #REQUIRED>

Otherwise, you get overlapping ID values for whatever reason - you included a
section from another document from the same namespace for instance. The DTD has
never been an ideal place to define ID and IDREFs, IMHO - it lacks scope. It
provides you with a suggestion, based on a certain configuration of a document.
It lacks dynamism.
