  Just be careful that this operation isn't formally defined from
a standard point of view. It's is more or less equivalent to validating
the document with just a 
 <!DOCTYPE root_elem SYSTEM "external DTD reference">
declaration. That should be fine with an entity, but it does ignore all
DTD declarations if used against a complete document, i.e. internal subset
informations would be lost.
