In Saxon, NodeInfo.compareOrder is used to determine, whether a node is already contained in a union set or not. For different nodes it must return a value != 0. It should consider the position of the nodes in document order. The new implementation uses now the position of the nodes (begin line, begin column) to determine the order. It might fail, if the position of the nodes are not correct.
