[Css-csts] more procedure identifier questions

[John Pietras]

Yves,

1. Section C.4.2 of the R-0.19 Framework states:

Whenever a new service (non-derived) is specified a new object
identifier is allocated directly under one of the branches
"prototypesIdentifiers" or "servicesIdentifiers". The allocated number
shall be complemented with three sub-numbers:

                                       i.          (service
name)DerivedServices: to register services derived from the specified
service;

                                      ii.          (service
name)ExtServiceParameters to register parameters syntax;

                                    iii.          (service
name)ExtServiceProcedures to register derived procedures for this
service.

 

The name of the last sub-number, "(service name)ExtServiceProcedures",
and its definition, "to register derived procedures for this service",
imply that this sub-number is to be used only for procedures that are
derived from other procedures. What sub-number should be used for
service-specific procedures that are not derived from other procedures?
If the intent is for this sub-number to be used for any procedures for
the new service, it might be more clear to call it "(service
name)serviceProcedures" and define it as "to register procedures for
this service". If the intent is for this sub-number to be used only for
derived procedures, then an additional sub-number needs to be defined,
e.g., "(service name)serviceSpecificProcedures", defined as "to register
procedures that are created for this service without derivation." I
personally don't see any reason to use two sub-numbers here, and so
suggest taking the "(service name)serviceProcedures" approach.

 

2. The same ambiguity exists in section C.4.3, regarding procedures for
derived services.

 

3. The object identifiers for both new and derived services (sections
C.4.2 and C.4.3, respectively) "shall be complimented with three
sub-numbers". No actual values are specified for those sub-numbers,
e.g., the XYZ service may assign its derived services the object
identifier

      xyzDerivedServices   OBJECT IDENTIFIER ::= {xyz  7}

and the MNO service may assign its derived services the object
identifier

      mnoDerivedServices   OBJECT IDENTIFIER ::= {mno  13}

 

For simplification in explanation (especially in the Guidelines), can we
simply assign these sub-numbers? That is, for example, DerivedServices
will always get "1", ExtServiceParameters will always get "2", and
ExtServiceProcedures (ServiceProcedures?) will always get "3". Some of
the sub-numbers may not get used for a given service (I would expect
DerivedServices to be used the least frequently, so maybe we should
assign it "3") but I don't think that is any problem. 

 

Best regards,

John
