It is ill-formed to use a -- in a comment in XML, "for compatibility"
(that is, there is no real technical reason, but it was illegal in
SGML, and to make XML a strict SGML subset, XML must carry forward
this restriction).

In any case, it is not "SAX" which reports this problem, but the
underlying XML parser.
