RE: retain/rebuild unparsed entities in internal subse

There's nothing in XSLT (or in Saxon) to make this information available.
You could try writing your own SAX filter between the XML parser and the
XSLT processor, which could make this information available by translating
it into elements in some special namespace, for example.
