Bootstrapping APIs for JAXP parsers. This is the first portable API defined for bootstrapping DOM.

JAXP parsers bootstrap in two stages. First is getting a factory, and configuring it. Second is asking that factory for a parser.

The SAX bootstrapping support corresponds to functionality found in the org.xml.sax.helpers package, except that it uses the JAXP two stage bootstrap paradigm and that the parser that's bootstrapped is normally wrapping a SAX parser rather than exposing it for direct use.
