public class InScopeNamespacesFn
extends SystemFunction

Implementation of the saxon:in-scope-namespaces extension function. Introduced in 10.0. Returns a map of prefixes to URIs representing the in-scope namespaces of a supplied element node. saxon:in-scope-namespaces($E) is equivalent to map:merge(in-scope-prefixes($E) ! map{., namespace-uri-for-prefix(., $E)}), but more efficient.
