-- The mandatory support on the IPMIdentifier components is more important
-- in MMS than in IPMS. The user component, ORName of the originating UA is
-- mandatory. Local IPMIdentifier is made up of 2 concatenated string
-- separated by a space both generated by the originating UA, a serial
-- number and the filing time (the time the message generation is finished)
-- in UTC time format. The minimum length of 15 is because both a date/time
-- stamp in UTC format including seconds and a serial number, plus the space
-- delimiter are mandatory. The smallest acceptable UTC date/time stamp
-- is 13 (ddmmyyhhmmssZ).
