This construct is perfectly acceptable.

As quoted, a parameter entity _reference_ is forbidden outdie a DTD.
What you have here is a parameter entity _declaration_ in the internal 
subset, and a parameter entity _reference_ in the external subset.

They're both inside the DTD, as well (everthing in the !DOCTYPE declaration 
that's between [ square brackets ] is the internal subset).

This might be a bug on the part of XML4j or XMLSpy.
