This [[Module Library|XQuery Module]] contains functions for manipulating maps. The following documentation is derived from an [http://www.w3.org/TR/xpath-functions-30/ XQuery 3.0 Functions and Operators] working draft proposal written by [http://en.wikipedia.org/wiki/Michael_Kay_(software_engineer) Michael H. Kay], and is not part of the official recommendation yet.
{{Mark|Version 7.7.1}}: In the new map syntax, the {{Code|map}} keyword is ommitted, and a colon is used as key/value delimiter (e.g.: <code>{ 'key' : 'value' }</code>). The new syntax will be officially introduced with XQuery 3.1. The old syntax (<code>map { 'key' := 'value' }</code>) is still supported.
