## Package com.saxonica.functions.map Description

This package implements maps, a Saxon extension to the XSLT and XQuery specification that provides a dictionary-like data structure.

Maps are immutable, so that adding a new entry to a map creates a new map.

The entries in a map are (Key, Value) pairs. The key is always an atomic value; the value may be any XPath sequence.

There are functions (each supported by its own implementation class) to create a new map, to add an entry to a map, to get an entry from a map, and to list all the keys that are present in a map.
