public class MapRemoveFunctionIterator
extends HybridRuntimeIterator

W3C XPath/XQuery map:remove: map:remove($map as map(*), $keys as xs:anyAtomicType*) as map(*). Removes all entries whose key is the same-key as any supplied key (op:same-key). This built-in is local execution only (consistent with other map/array accessors).
