[Css-csts] Procedure instance number of Association Control procedure?

[Yves.Doat at esa.int]

Dear John,
In my view the section 2.5.3 should address the issue. This section states:



Every  service  includes  the Association Control procedure (see 4.3). Only a
single  instance  of  the Association Control procedure exists throughout the
lifetime of a transfer service instance.


In  addition  to the Association Control procedure a service may comprise any
number  of  further procedure types and may use one or more instances of each
procedure  type.   However,  one  single procedure instance is designated the
prime  procedure  of the service.  All other procedure instances are referred
to as secondary procedures.


NOTE    —  The  prime  procedure (instance) can be of the same type as one or
         more secondary procedure instances.


The  prime  procedure  (instance)  of  a  service  should reflect the primary
purpose  of  the  service.  In practical terms it determines the state of the
service and as such determines the orderly association release as detailed in
2.6

From the text I understand that the association control procedure cannot be a
prime procedure (last paragraph) and therefore must be of secondary procedure
type. Its number should therefore be "1".
A clear statement could be added, e.g. the following sentence at the end of
the 2nd paragraph:
"The association control procedure is a secondary procedure."

Please let me know your opinion.
I would also appreciate an answer of the prototype developers: what value did
you use?

Best regards
Yves

CSTSWG colleagues –
We have stated that the prime procedure instance get procedure instance
number 0, and that secondary procedure instances are numbered
1 .. <number of secondary instances>. What should be the procedure instance
number for the Association Control procedure instance, which is neither prime
nor secondary?
