I don't know how to have foo.xml cannot contain both the entity
declarations and references.  My example only works if foo.xml
contains only entity declarations, that you can reference in your
document afterwards (basically making foo.xml a library of entities).

That's not what I meant (I basically just modified a bit the original
example), but that would be doable I think (untested).

Another approach I think of would be to use sub-documents, but I don't
really know what this concept is about yet, and don't know whether XML
supports this SGML concept.  Does someone has any clues about that ?
