- How Xerces-J uses an XPath 2.0 engine for XML Schema 1.1 assertions
and type alternatives?
+ How Xerces-J uses an XPath 2.0 engine for XML Schema 1.1 assertions
and CTAs?
- XML Schema 1.1 'assertions' and 'type alternatives' require an
http://www.w3.org/TR/xpath20/";>XPath 2.0 processor
- for evaluation. For XSD 1.1 assertions, full XPath 2.0 support is
required. For XSD 1.1 type alternatives, XML schema engines can
- provide full XPath 2.0 support or they can implement a smaller XPath
2.0 subset, as defined by the XSD 1.1 language.
- Within the type alternatives implementation, Xerces-J first attempts
to compile the XPath expression with a native Xerces "XPath subset"
- parser. If parsing with the native Xerces "XPath subset" parser
fails, Xerces-J transparently switches over to another processor which
- supports all of XPath 2.0. The native processor in Xerces-J was
written for efficiency, so you will likely get better performance if your
- XPath expressions fall within the minimum subset defined by the XML
Schema 1.1 specification. For full XPath 2.0 evaluation
- (for XSD 1.1 'assertions', and optionally for 'type alternatives'),
Xerces-J uses the
- http://wiki.eclipse.org/PsychoPathXPathProcessor";>Eclipse/PsychoPath
XPath 2.0 engine.

- Xerces-J bundles a PsychoPath XPath 2.0 jar (which requires JDK 1.4
or later).
