+  * This class represents the address of a communications end-point.
+  * It consists of a type that describes the communication mechanism
+  * and an address contents determined by an RefAddr subclass.
+  *<p>
+  * For example, an address type could be "BSD Printer Address",
+  * which specifies that it is an address to be used with the BSD printing
+  * protocol. Its contents could be the machine name identifying the
+  * location of the printer server that understands this protocol.
+  *<p>
+  * A RefAddr is contained within a Reference.
+  *<p>
+  * RefAddr is an abstract class. Concrete implementations of it
+  * determine its synchronization properties.
