6.1 Requirement
The Requirement specification is in subclause 4.2 Rules.
6.2 IS-level
There is no text specifically written related to IS-level specification for BC systems. The two system context diagrams of subclauses 5.2 and 5.3 would be necessary and sufficient to describe the management services provided by EM to support the so-called Old IRPManager and New IRPManager.
6.3 SS-level
6.3.1 CORBA
For CORBA Solution Set, the IRPAgent level (see subclause 5.3) context would be used.
6.3.2 Void
6.3.3 File format description XML
Editor’s Note: This part is FFS.
6.3.4 File format description ASN.1

Annex A (informative):
BC and Conformance Tests
This annex illustrates that:
– an IRP, implementing a new-version IRP specification that is BC to an old-version IRP specification, may or may not be compliant to the old-version IRP specification.
Figure A.1: BC and Conformance Tests Scenario
Suppose 3GPP has an older-version IRP specification (the "Old-version IRP specification" box) and there is a valid/correct implementation (the "Old-IRP" box).
Suppose also that 3GPP produce a "New-version IRP specification" by extending the "Old-version IRP specification" using the BC-rules.
The "New-IRP" should interwork with IRPManager that uses the "New-version IRP specification".
This "New-IRP" should also interwork with IRPManager that uses the "Old-version IRP specification".
The "Old-IRP" should pass the conformance test that is based on (see "depend" relation) the "Old-version IRP specification".
Likewise, the "New-IRP" should pass the conformance test that is based on the "New-version IRP specification".
However, this "New-IRP" may not be able to pass the conformance test that is based on "Old-version IRP specification" (see "test (should fail)" relation).
Likewise, the "Old-IRP" should not be able to pass the conformance test that is based on "New-Version IRP specification".
