 /**
  * Loads a pair from the supplied XML element.

  * @param graph the graph which elements to load Ideally, I need to match string IDs loaded to
  *     those of the graph but this is not done because
  *     <ul>
  *       <li>graphseries used to mangle names of vertices, now this should not happen often (and
  *           if I use relabelling when loading graphs, this would never happen).
  *       <li>this method is expected to be general - purpose hence we do not expect a matching
  *           graph to be present.
  *       <li>matching was only needed when loading a compatibility table from a graph - graph
  *           loader now does the matching after reading pairs.
  *     </ul>
  *
  * @param elem element to load from
  * @return loaded state pair.
