Synopsis

                     string generate-id(node-set node)
string generate-id( )

The generate-id( ) function returns a string that can be used as the value of an ID type attribute. This function always produces the same string for the same node and a different string for a different node. If the node-set contains more than one node, then only the first node in the set is considered. If the argument is omitted, then the node-set is set to the context node. If the node-set is empty, then the empty string is returned.
