Me too. I'd like to get it as a convenient option.

http://www.w3.org/TR/REC-xml.html#proc-types
"Non-validating processors are required to check only the document 
entity, including the entire internal DTD subset, for well-formedness. 
[Definition: While they are not required to check the document for 
validity, they are required to process all the declarations they read in 
the internal DTD subset and in any parameter entity that they read, up 
to the first reference to a parameter entity that they do not read; that 
is to say, they must use the information in those declarations to 
normalize attribute values, include the replacement text of internal 
entities, and supply default attribute values.]"

AFAICS: REXM should resolve entities and much more things that are in 
the internal subset.
