(Item 008393)  Update DLUR processing to unextend an extended BIND              
------------------------------------------------------------------              
Jim Cobban of NORTEL discovered an omission in the DLUR architecture            
description of how to unextend an extended BIND.  While the CVs were            
removed, the SLU name was incorrectly left in the RU.                           
                                                                                
When NCP unextends an extended BIND, it determines the number of bytes          
to remove from the end of the non-CV portion of the BIND RU to make it          
unextended.  This number includes truncation of trailing zeroes and the         
SLU name (for non-negotiable BINDs).                                            
                                                                                
Therefore, the proposed solution is to update the architecture to state         
the DLUR processing for unextending an extended BIND involves:                  
                                                                                
     - removing all keyed control vectors                                       
     - turning off the CVs included indicator                                   
     - truncating trailing zeroes and the SLU name (for non-negotiable          
       BINDs)                                                                   
     - updating the new length of the BIND RU
