Yes, but by making it part of the core SAX protocol for setting
features, we guarantee universal support for it.  A parser that knows
itself to be naive about namespaces can load the NamespaceFilter and
push it on top of itself, almost transparently to the application.
Otherwise, every application that wants namespace support needs
specialized knowledge about how to recover from SAXNotSupportedExn.
