Technical Summary
 
  These documents creates an IANA registries for SIP header field
   parameters and parameter values, and SIP/SIPS uri parameters
   and parameter values.  It also lists the already existing
   parameters and parameter values to be used as the initial entries for
   this registry.

   The purpose of this to to update RFC 3427 and minimize problems
   from duplicated parameters and problematic values.

Working Group Summary
 
 There was strong support of this registry.  The working group pushed for 
 adding the parameter values registry.  A determination was made that 
 such a registry could become large, so the compromise design was decided
 on:  when parameter values are registrable, the registry for the parameter
 flags this, and points to the RFC documenting their set of values.
 
Protocol Quality
 
 The document review for the IESG was done by Allison Mankin and IANA
 reviewed during Last Call without finding problems. 
There was a large amount of review by the working group.
