Entities and Expat (was Re: Confused about & in entity literal)

An external entity reference needs a declaration:

<!ENTITY copy SYSTEM "http://blah.blah.blah/blah.xml">

If you want your application to "just know" about some entities which you
have failed to define anywhere, I don't think that documents relying on
that behavior would even be considered well-formed.

How about putting:

<!ENTITY copy "&#38;copy">

and the like into your document?
