00029 //       Class : DCParameter
00030 // Description : Represents the type specification for a single
00031 //               parameter within a field specification.  This may be
00032 //               a simple type, or it may be a class or an array
00033 //               reference.
00034 //
00035 //               This may also be a typedef reference to another type,
00036 //               which has the same properties as the referenced type,
00037 //               but a different name.
