RE: [xsl] does xsl:output method xml guarentee well formedness?

["Michael Kay" <mike@xxxxxxxxxxxx>]

In the presence of character maps or disable-output-escaping, there is no
guarantee that the serialized result of a transformation will be
well-formed.

This is stated at the end of the introduction to section 5 of the
serialization spec,
