That is your problem.  You need to create a DTD internal subset
declaration, like this:

<!DOCTYPE root-element-name [
	<!ENTITY copy "&#38;copy;">
	<!ENTITY aelig "&#38;aelig;">
	etc. etc.

That will cause the entity reference "&aelig;" to expand to the
string "&aelig;", which seems to be what you want.

I was talking about a different case:  entity references within
entity declarations, not entity references within the document instance
itself.  This is really only of concern to parser writers.
