Re: [sca-policy] ISSUE-104: Clarify meaning of 'does not have to supportintents' in Conformance section

[Mike Edwards <mike_edwards@uk.ibm.com>]

Folks,

In my opinion, it should be valid for
a user to write a composite using any of the intents listed in the Policy
specification.

It is also valid for a given runtime
not to have policy support for any of the intents.  eg there is no
support for signing
messages so that integrity intent cannot
be honoured.

In this case, the Composite documents
are VALID - they cannot be rejected because they contain the intents.
However, the runtime can raise an error
and refuse to deploy/run the composite because the intents cannot be
honoured.  The same would be true
if a PolicySet were contributed and used, but the set of policies in the

policySet could not be provided either
by the container or by the binding implementations available with that
runtime.

In my opinion, what needs changing here
is the line in section 11 (Conformance) - it needs to be expanded to say
much as I have said here.

TARGET: SCA Policy FW spec CD02/PR01

DESCRIPTION: 
Section 11 Conformance states (line 2346):
'The implementation does not have to support any intents listed in this
specification, and MAY reject SCDL documents that contain them.'

Also consider that POL30024 says the following:
'An SCA Runtime MUST include in the Domain the set of intent definitions
contained in the Policy_Intents_Definitions.xml described in the appendix
"Intent Definitions" of the SCA Policy specification.'

What does it mean to support an intent? Section 11 needs to be clarified.

PROPOSAL: 
None.


This completes my outstanding AI: 20090727-01: status=pending: Dave to
raise an issue against the Policy spec to deal with the inconsistency relating
to the support of intents.
