Klaus,

In SS7 Hop Counter is optional in CR, mandatory in XUDT/XUDTS/LUDT/LUDTS,
but is not present in any other messages (that includes UDT/UDTS).  No
procedure which includes Hop Counter can be made mandatory at all times.
The procedure is optional even in SS7.

It is clear that Hop Counter should be optional in CORE, CLDR and CORE,
as it is in SS7.
