Description: In GraphML there may be data-functions attached
             to graphs, nodes, ports, edges, hyperedges and
             endpoint and to the whole collection of 
             graphs described by the content of <graphml>. 
             These functions are declared by <key> elements
             (children of <graphml>) and defined by <data>
             elements.
Occurence: <graphml>, <graph>, <node>, <port>, 
           <edge>, <hyperedge>, and <endpoint>.
