0021 **   some constants used in accessing, interpreting or
0022 **   storing data in the packet header.  All constants
0023 **   defined here are for fields with version independent
0024 **   values.  Also defined here are the default values for
0025 **   all of the version independent fields.  Version dependent
0026 **   values for the Version 1 packet header are found in
0027 **   packetHdrV1.h.  Value for the fields defined in the
0028 **   data descriptor are found in dataBlockHdr.h.  All fields
0029 **   have default values listed, even those which are
0030 **   typically user specified.
