Description

It would be useful to allow the default piccolo parser to be replaced by other SAX2 conformant parsers that may other more features/performance without having to make application code changes.

This can be done by some minor changes to the Store Locale.java mechanism that caches piccolo parsers per thread. In a trial implementation (see attached patch) an xmlbeans specific system property is added which has the same meaning as the 'org.xml.sax.driver' property, i.e. it specifies the name of a org.xml.sax.XMLReader class. If the property is set this parser is instantiated instead of a piccolo parser.

The patch passes checkintest when the property "org.apache.xmlbeans.xmlreader" is set to "com.sun.org.apache.xerces.internal.parsers.SAXParser" on a jdk1.5.0_15 on WIN32.
