Although it may not formally be part of SAX, I think it will be extremely
valuable to have reference library implementations of parts of the spec.
For example, what is a valid Name in XML? You have to treat a large number
of special cases for characters, and are extremely vulnerable to revisions
of the spec (this is an area where I am sure minor revisions will happen).
So a set of library classes of the type:
	public static boolean isValidName(String name);
	public static String getCaseSpaceNormalizedAttval(String value);
would be extremely valuable. We can then delegate part of the prose to
these implementations.
