well XML doesn't have SDATA entities so really it doesn't have any
support for unexpanded entities. An entity reference in a document
without a doctype is a fatal error (that's also why schema doesn't allow
the definition of entities). If youhave an entity ref and a DTD with an
external subset that doesn't define the DTD that's only a validity error
not a fatal well formedness error (on the grounds that a non validating
parser might not read the dtd and so know the enity wasn't defined).

so

isn't really true. If XSLT wanted to try to ensure output was well formed
XML it would have to have a better model of DTD and dcotype information
than it currently has if it wanted to output entity refs.
