The problem is that external entities must be separately validatable, right?
How do any of these solutions help? Unless, of course, the entities can only
be validated by the editor.

Seems like a more appropriate solution would be to use a validator that
allows the DTD to be specified outside the document. (And an editor that
allows same.)
