Technical Summary 

This memo updates RFC 2446, iTIP.  While no new protocol elements
are introduced, a number are deprecated, while others are clarified.
The examples are also improved.

Working Group Summary 

There is rough consensus to move the document forward, and it wasn't
all that rough.  We had one minor issue relating to a constraint table,
as to readability, but that is editorial preference.
Document Quality 

There are existing implementations, and a number of vendors plan to
implement the specification.  We gratefully acknowledge Nigel Swinson for
his review of the constraint table.

RFC Editor Note

adding to the beginning of Section 7.3:

   New "REQUEST-STATUS" values can be registered using the process    
   described in Section 8.2.1 of [RFC5545].
