Hi, Tom.

Excellent... so I think we are done with dot-x.

One additional point that I was going to write into the main 
minorversion2 review relating to referencing  the requirements RFC 
7204.  rpcsec-gssv3 also references the requirements RFC but the amount 
of info that is needful to  support implementers seems to be mostly in 
minorversion2.  Would it be possible for you and Andy to work out if 
anything extra is really needed in minorversio2 (about guest mode 
primarily I think) so that the requirements reference is not needed and 
rpcsec-gssv3 can just reference minorversion2 for all info on the 
modes?  I wasn't sure what, if anything, extra was needed in minorversion2.

The XDR specification appears to be a superset of the v4.1 XDR specification and combines a correction of the five remaining discrepancies between v4.1 and v4.0bis ( definition and use of the NFS4_OTHER_SIZE constant, addition and use of the ascii_REQUIRED4 type, modification of the typedef of linktext4). The additions of the 4.2 interface appears to match the specification in draft-ietf-nfsv4-minorversion2-39 except for two attribute typedef  items mentioned below.  One discrepancy would have no operational effect as the type used in the other draft  is an alias for the type used here but the clone_blksize error changes the size of the type.

>> Observation:  It might be useful to note that this XDR specification is fully upwards compatible with the v4.0bis with the minor exception of the clientaddr4 structure which has been replaced by (strictly, aliased to) netaddr4 which has the same members with the same purposes but the names have changed (r_netid -> na_r_netid, r_addr ->na_r_addr).  This effectively fully reconverges the v4.0bis and v4.1 strands of the XDR.
