Adding entities to XML without DTDs would break the compatibility of
new documents with old parsers. I think entities alone are not worth
such a discontinuity.

If there's a discontinuity that makes new documents potentially
incompatible with old parser (but old documents stay compatible with
new parsers), I think it makes sense to move to well-defined
non-Draconian processing (XML5-style) while at it.
