... and SVG as well, but those DTDs aren't subject to change based on the
contents or requirements of the instance. Using a more document-oriented DTD,
inclusion of a fragment of data from a different namespace involves modifying
the DTD. This may not be practical even though it is possible.

There's a fair-sized canyon between marginally compatible and practically
compatible too, but admittedly, only under some circumstances.
