+
+  A paramref is similar to a fieldref, but it refers to the value of

+  So, it refers to a field outside of the structure where it is defined.
+  This has the following consequences:
+  * The generator cannot deduce its type.
+    So, it is mandatory to specify its type.
+  * The identifier-name must not be used as a field in the structure
+    which contaons the paramref.
+
+  For an example, see struct "DeviceTimeCoord" and request/reply
