Within XML 1.0, there are various things that non-validating parsers
are allowed to do (or not do). A way of querying any particular parser
to find out whether it does those things or not would be very useful.
For example, a parser is allowed to disregard attribute types and
claim that all attributes are CDATA. If your application depends on
getting ID and IDREF types correct, you could query a parser to see
if it can do that --- and if not, tell the user to pick another parser.
So these are not so much SAX features as XML features.
