This schema is available for use under the conditions of the W3C Software License published at https://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. Prefixed-QName matches only QNames with a non-null prefix: that is, only QNames with a colon. Qualified-EQName matches only EQNames with a non-null namespace name.
