Technical Summary

   This document defines a new DNS OPCODE for DNS Stateful Operations
   (DSO).  DSO messages communicate operations within persistent
   stateful sessions, using type-length-value (TLV) syntax.  Three TLVs
   are defined that manage session timeouts, termination, and encryption
   padding, and a framework is defined for extensions to enable new
   stateful operations.  

Working Group Summary

   The working group spent a significant amount of time on this
   document, as it adds persistence to DNS "connections".
   However, after several iterations, the working group came to
  consensus on the document, and strong consensus to move forward. 

Document Quality

  The document is clear and easily read.
   It defines capabilities and provides functionality to be leveraged
   by other protocols.
   There are currently no existing implementations of the protocol. However, 
   this work is being leveraged in another working group on DNS Service Discovery.
   Now that this draft is moving forward, final implementations can begin to
