XML Schema Processing
Schema processing is available only with the enterprise version of the product,
Saxon-EE, available from http://www.saxonica.com/.
Saxon can be used as a free-standing schema processor in its own right, either from
the command line or from a Java application. In addition, Saxon can be used as a
schema-aware XSLT processor or as a schema-aware XQuery processor.
Saxon-EE supports the schema validation APIs in JAXP 1.3, as well as its own native APIs.
