+/**
+  * This class is used to store the values for identity constraints.
+  *
+  * Sketch of algorithm:
+  *  - When a constraint is first encountered, its values are stored in the
+  *    (local) fIC2ValueStoreMap;
+  *  - Once it is validated (i.e., when it goes out of scope), its values are
+  *    merged into the fGlobalICMap;
+  *  - As we encounter keyref's, we look at the global table to validate them.
+  *  - Validation always occurs against the fGlobalIDConstraintMap (which
+  *    comprises all the "eligible" id constraints). When an endelement is
+  *    found, this Hashtable is merged with the one below in the stack. When a
+  *    start tag is encountered, we create a new fGlobalICMap.
+  *    i.e., the top of the fGlobalIDMapStack always contains the preceding
+  *    siblings' eligible id constraints; the fGlobalICMap contains
+  *    descendants+self. Keyrefs can only match descendants+self.
