Section 2 says:

   /// /*
   ///  * Program number is in the transient range since the client
   ///  * will assign the exact transient program number and provide
   ///  * that to the server via the SETCLIENTID operation.
   ///  */
   /// program NFS4_CALLBACK {

It should say:

   /// /*
   ///  * Program number is in the transient range since the client
   ///  * will assign the exact transient program number and provide
   ///  * that to the server via the CREATE_SESSION or
   ///  * BACKCHANNEL_CTL operations.
   ///  */
   /// program NFS4_CALLBACK {

Notes:

SETCLIENTID operation is NFSv4.0 specific operation. NFSv4.1 uses CREATE_SESSION or BACKCHANNEL_CTL operation for setting backchannel parameters.
