I don't see any justification for not classifying it as valid.

Certainly the entity is not well-formed, but since it is not referred
to it does not affect the well-formedness of the document.

There is also erratum 13:

  To the paragraph before production [30], add "The external subset
  and any external parameter entities referred to in the DTD must
  match the production for extPE. See 4.3.2 Well-Formed Parsed
  Entities".

so there is a "must" (and note the wording: PEs *referred to* must
match extPE).
