XQuery 1.0 and XPath 2.0 Data Model

An abstract model which binds XML Query into the family of XML Recommendations.

Two major goals:

1. defines the information input to an XSLT or XQuery processor
2. is at the basis of the XSLT 2.0, XPath 2.0 and XQuery 1.0 languages

It contains:

• XML Infoset plus:
  • usage of functions/operators (eg, xf:get-local-name)
  • infoset items are enriched with accessors
  • support for XML Schema data types in describing infoset properties, for example

Developed jointly with the XSL Working Group
