public class NamespaceUriFunction extends Object implements Function
4.1
string namespace-uri(node-set?)
The namespace-uri function returns the namespace URI of the expanded-name of the node in the argument node-set that is first in document order. If the argument node-set is empty, the first node has no expanded-name, or the namespace URI of the expanded-name is null, an empty string is returned. If the argument is omitted, it defaults to a node-set with the context node as its only member.
NOTE: The string returned by the namespace-uri function will be empty except for element nodes and attribute nodes.
