It would be tempting to say it had also to be valid xml using a catalog supplying some minimal dtd (which would also ensure no entity references were used) but unfortunately using a catalog for that form requires a optional feature of the xml catalog spec (defaulting a dtd based on top level element name) Most likely though I should document this as a restriction rather that change the schematron, it's not reliable to reload the same document via unparsed-text (the original document may not be available if for example it was originally supplied as a stream on standard input.) again, the polyglot spec is wrong to make this requirement (as html/xml parsing is not affected, which is why it is hard to check it with schematron) so perhaps the correct fix here is to enter a bug on the spec.
