Subject: NEW ISSUE: Is the policy (specified in intentMap) from all of multiplequalified intents in effect?
TARGET: SCA Policy Framework
DESCRIPTION:
Consider a policySet that provides intent A with default A.X in an intentMap. The SCDL contains:
<binding.myBinding requires="A.Y A.Z" policySets="PolicySetThatProvidesA"/>
Clearly we override A.X but with A.Y or A.Z, or is it an error. The spec does not say. The decision comes down to
a) additive (A.Y and A.Z)
b) mutually exclusive (A.Y or A.Z)
We don't have a mechanism to express either (a) or (b).
Once we have the mechanism laid down, then the rule gets clear:
a) For additive intents, the default intent is replaced by all the specified intents and all of the selected policies
get applied
b) For exclusive intents, it is an error for A.Y and A.Z to be specified together.
PROPOSAL: none
PROVENANCE: SCA-248
