33  * Description:
34  *      NDMPv9, represented here, is a ficticious version
35  *      used internally and never over-the-wire. This
36  *      isolates higher-level routines from variations
37  *      between NDMP protocol version. At this time,
38  *      NDMPv2, NDMPv3 and NDMPv4 are deployed. NDMPv9 tends
39  *      to be bits and pieces of all supported protocol versions
40  *      mashed together.
41  *
42  *      While we want the higher-level routines isolated,
43  *      for clarity we still want them to use data structures
44  *      and construct that resemble NDMP. Higher-level routines
45  *      manipulate NDMPv9 data structures. Mid-level routines
46  *      translate between NDMPv9 and the over-the-wire version
47  *      in use. Low-level routines do the over-the-wire functions.
48  *
49  *      The approach of using the latest version internally
50  *      and retrofiting earlier versions was rejected for
51  *      two reasons. First, it means a tear-up of higher-level
52  *      functions as new versions are deployed. Second,
53  *      it makes building with selected version impossible.
54  *      No matter what approach is taken, there will be
55  *      some sort of retrofit between versions. NDMPv9
56  *      is simply the internal version, and all bona-fide
57  *      versions are retrofitted. v9 was chosen because
58  *      it is unlikely the NDMP version will reach 9
59  *      within the useful life of the NDMP architecture.
60  *
61  *      NDMPv9 could be implemented in a hand-crafted header (.h)
62  *      file, yet we continue to use the ONC RPC (.x) description
63  *      for convenvience. It's easy to cut-n-paste from the other
64  *      NDMP.x files. It's important that ndmp9_xdr.c never be
65  *      generated nor compiled.
