Bob, the short answer is yes, this is common practice in W3C specs. 
See the OWL DTD at http://www.w3.org/2002/07/owl for an authoritative example.
Make sure you have the "view source" option on, because many browsers will do the entity expansion already for you (!).

The longer answer is "yes, but": the entities need to be defined in the internal DTD part of the file,
that is, in the square bracketed part of the 

<!DOCTYPE rdf:RDF [ 
<!-- entity defs go here --> 
]>.

Applications are not obliged to process external DTD files as in in the old SGML days.

Hope this helps,

Jacco
