The class of XML Schema built-in types.

Subclasses of xsd-type provide the built-in types of XML Schema Part 2: Datatypes Second Edition as specified in Guidelines for using W3C XML Schema Datatypes with RELAX NG.

The XSD type library is named :|http://www.w3.org/2001/XMLSchema-datatypes|.

Parameters. All XSD types accept regular expressions restricting the set of strings accepted by the type. The pattern parameter is called "pattern". This parameter can be repeated to specify multiple regular expressions that must all match the data. As an initarg, specify :pattern with a list of regular expressions as an argument.
