This module is statically bound to the prefix "map".
- Description
The functions defined in this section use a conventional namespace prefix map, which is assumed to be bound to the namespace URI http://www.w3.org/2005/xpath-functions/map.
A map is an additional kind of item.
A map consists of a set of entries. Each entry comprises a key which is an arbitrary atomic value, and an arbitrary sequence called the associated value.
