Remember that SAX is a front-end to various parsers with various
philosophies, validating (XML4J), non-validating but external-entity-
reading (Aelfred), non-validating and document-entity-only (XP).

SAX provides methods, for parsers that wish to do so, to report on
declared notations and unparsed entities, since these features
provide actual extensions to the basic element/attribute model.
Element and attribute list declarations cannot be reported through
SAX, since they are reckoned inessential.
