* Introduction on maps moved to [[XQuery 3.1#Maps|XQuery 3.1]].
* Removed: support for collations (in accordance with the XQuery 3.1 spec).
* Updated: aligned with latest specification: compare keys of type {{Code|xs:untypedAtomic}} as {{Code|xs:string}} instances, store {{Code|xs:float}} or {{Code|xs:double}} value {{Code|NaN}}.
