I have released beta code for two SAX parser filters. A parser filter looks like a standard SAX parser, but relies on an underlying real parser to do the work, and adds some extra service.

NamespaceFilter provides an implementation of the XML Namespaces WD. All element and attribute names are resolved to the form "URI^localpart", where URI may be null. The circumflex character is not legal in either URIs or localparts. The non-SAX methods mapElementName() and mapAttributeName() convert element or attribute names to "URI^localpart" form according to the current set of namespace prefixes.

InheritanceFilter provides support for inheritable attributes. By default, only xml:space and xml:lang are inheritable, but applications may call the non-SAX method inheritable() to specify other inheritable attributes.

The abstract class ParserFilter provides the basic mechanism for writing parser filters.
