Hi,

Looking at this latest version I have a comment.

section 14.4 defines the SPST registry.

Why isn't is adding the ETSI defined values from the start. If they are
known and have well known reference I don't see any issues with putting
in the values into the registry at its creation.

Value           Name                         Reference
   -----           ----                         ---------
   1               Synchronization Client       section 7 of [RFCXXXX]
   2               <Appropriate Name>           [TS183063]
   3               <Appropriate Name>           [TS183063]
   4               <Appropriate Name>           [TS183063]


Cheers

Magnus
