| I don't agree that these entities are illegal in XML.  Let's take an example:
| <!ENTITY % local.appendix.class "">
| <!ENTITY % appendix.class	"Appendix %local.appendix.class;">
| <!ELEMENT Article (ArtHeader, ToCchap?, LoT*, (%bookcomponent.content;),
| 		((%nav.class;) | (%appendix.class;) | Ackno)*) >
| Parameter entity references in the replacement text of an internal parameter

| reference just fine.

But local.appendix.class is still "" if not declared elsewhere, and its
declaration doesn't fulfill the %Name token requirement of production 63, 
if I read it correctly.
