+    A MDDCollIter represents an iterator for a persistent MDD collection.
+    If a collection is changed (elements are removed or added to/from the 
+    collection) between creation of an iterator for it and the execution of
+    other operations on the iterator, the behavior of the istent Iterator 
+    is undefined.
+    The {\tt MDDColl::createIterator()} for the object to be scanned should 
+    be used to create a new iterator object.
