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.
With {{Mark|Version 7.7.1}}, the map syntax has changed (the old syntax is still supported): the {{Code|map}} keyword is omitted, and a colon is used as key/value delimiter (e.g.: <code>{ 'key' : 'value' }</code>). The new syntax will most probably be standardized with XQuery 3.1.<br/>
