Subject: [OASIS Issue Tracker] Commented: (SCAPOLICY-2) Simplify policySet model?
[ http://tools.oasis-open.org/issues/browse/SCAPOLICY-2?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=29416#action_29416 ] David Booz commented on SCAPOLICY-2: ------------------------------------ opened Feb 1,2010 telecon > Simplify policySet model? > ------------------------- > > Key: SCAPOLICY-2 > URL: http://tools.oasis-open.org/issues/browse/SCAPOLICY-2 > Project: OASIS Service Component Architecture / Policy (SCA-Policy) TC > Issue Type: Bug > Components: 1.2 Spec > Affects Versions: V1.2 > Reporter: David Booz > > Target: SCA Policy FW spec V1.1 (cd02-rev7) > Description: > As background, policySets can be attached either directly to SCDL > elements of using External Attachment on SCDL elements selected > by the XPath in the attachTo attribute. The following paragraph > discusses the interaction between these two attachment mechanisms. > "SCA runtimes MUST support at least one of the Direct Attachment and > External Attachment mechanisms for policySet attachment. [POL40010 > <#POL40010>] SCA implementations supporting only the External Attachment > mechanism MUST ignore the policySets that are applicable via the Direct > Attachment mechanism. [POL40011 <#POL40011>] SCA implementations > supporting only the Direct Attachment mechanism MUST ignore the > policySets that are applicable via the External Attachment mechanism. > [POL40012 <#POL40012>] SCA implementations supporting both Direct > Attachment and External Attachment mechanisms MUST ignore policySets > applicable to any given SCA element via the Direct Attachment mechanism > when there exist policySets applicable to the same SCA element via the > External Attachment mechanism [POL40001 <#POL40001>]." > The two ideas that came up were: > 1. If both Direct Attachment and External Attachment are used, the > policySets attached by these two mechanisms are unioned together. > Mike pointed out that this removes that capability of overriding Directly > attached policySets by EXtrenally attached policySets. > 2. Remove the Direct Attachment mechanism for policySets. > Some may feel that it is a bit late in the spec cycle to be making such > fundamental changes but let's have a discussion and decide what we want to do. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
