+* The ODMG Set collection interface.

+* multiple elements with the same value. An implementation typically is very
+* efficient at determining whether the collection contains a particular value.
+* <p>
+* All of the operations defined by the JavaSoft <code>Set</code>
+* interface are supported by an ODMG implementation of <code>DSet</code>,
+* the exception <code>UnsupportedOperationException</code> is not thrown when a
+* call is made to any of the <code>Set</code> methods.
