Saxon extensions to XML Schema 1.1

The XSD 1.1 Recommendation allows implementations to define their own primitive types and facets.

At present Saxon provides one additional facet, saxon:preprocess.

Saxon extensions to the XML Schema Language are implemented in the Saxon namespace http://saxon.sf.net/:

• Messages associated with assertions and other facets

• The saxon:preprocess facet

• Saxon extensions to XSD uniqueness and referential constraints
