This is my reading of the spec too -- ASCII control characters (except
tab, line feed and carriage return) can not be represented natively in
XML.  One could encode the data as base64 or whatever and put that in
the XML.  I ran into this problem before when trying to update from an
obsolete XML parser that wasn't standards compliant to one that
enforces the spec.
