+// Since the reflection interface for DynamicMessage is implemented by
+// GenericMessageReflection, the only thing we really have to test is
+// that DynamicMessage correctly sets up the information that
+// GenericMessageReflection needs to use.  So, we focus on that in this
+// test.  Other tests, such as generic_message_reflection_unittest and
+// reflection_ops_unittest, cover the rest of the functionality used by
