      This is a schema for serialization parameters for
      XSLT and XQuery Serialization 3.0.

      This schema is available for use under the conditions of the
      W3C Software License published at
      http://www.w3.org/Consortium/Legal/copyright-software-19980720

      It defines a schema for XML Infoset instances with which a user of
      a host language MAY specify serialization parameters for use in
      serializing an instance of the XQuery and XPath Data Model.  It
      also provides hooks that allow the inclusion of implementation-
      defined serialization parameters and implementation-defined
      modifiers to serialization parameters.
