Details
If the supplied node is not an element, the function returns the empty sequence.
In other cases it returns a map from namespace prefixes to namespace URIs, giving all the
in-scope namespace bindings for the element. This is a more efficient way to obtain this information
than either the use of the namespace axis, or the XPath 2.0 functions in-scope-prefixes
and namespace-uri-for-prefix.
The map includes the default namespace, if there is a binding for the default namespace: the relevant entry in the map will have a key that is the zero-length string. The map does not include the implicit binding of the "xml" namespace.
