xs:boolean=xfi:u-equal-set( $left as node()*, $right as node()*)

Last updated on 06-03-2008 at 22:40:00.

Sets are formed from the items in each sequence, removing duplicates in the process of forming sets. Returns true if for every item in the left sequence's set there is a u-equal item in the right sequence's set, and the sets have the same count of members. (Because u-equal is defined by XBRL only for items, operation is restricted to nodes that are items.)
