III. Issues

New: "The known issues in XACML 3.0 CS 01":
  erik: http://lists.oasis-open.org/archives/xacml/201103/msg00054.html
  bill: http://lists.oasis-open.org/archives/xacml/201103/msg00055.html

   erik: all are in wiki page for viewing;
   hal: bill and hal think a new cs is appropriate; get wkg drafts,
	go to 15-day pub rev, would still be 3.0; cs reps pre-impl stage,
	expect some chgs before OS.
   erik: 2 concerns: would like weekly mtgs because there are so many
	detailed steps; would encourage more discussion in advance;
	things will be continuing;
   erik: proposes going weekly until next CS.
   tony: short notice for next week
   erik: agrees: start weekly after next mtg in 2 wks; want to have
	comments on wiki:

	1. accept as proposed (erik: www moving away from "duration",
		so difficult to mix months in for duration for some
		data types)
	2. chg schema as proposed; loosely defined in xml sch
	3. ldap not x500 coding; agree to add sample, but no fix reqd
	4. both english and haskell, in one case don't match, english
		appears to be correct (carried over from 2.0); related
		issue, prev f2f, didn't update haskell to more general,
		removed the haskell; some of haskell defns ref the
		haskell defns removed in 3.0, so incomplete; shouldn't
		be 2 defns of same thing; erik: english is generally
		the correct defn; for higher order suggest using only
		english; jan: not sure if such defns can be done in
		haskell, recommends english; erik will review english
		and remove the haskell;
	5. has been removed as not a problem
	6. if target indet, results of com-alg determines result; point
		is that new algs track possible results if not an error;
		that info kept as policy eval'd upwards; if target of
		policy uses ext-alg, what value does whole policy get,
		what type of ind, comb alg should be eval'd and final
		result would be from the comb alg. already well-defined
		for rules, only impacts policy, policysets;
		erik will draft proposed wording
	7. english is wrong, schema is correct, carryover from xacml 1.0,
		chg would be to remove condition from expression
	8. obligations: interpretations; greg: if you look at in detail,
		it actually appears correct; erik: can tweak language if
		still confusing. greg: not strictly wrong, but confusing.
		erik will look at greg's proposal
	9. erik: there are no accepted defns for what these "is-in" fcns
		mean for ip-addr or dns-name; erik: issue is equality
		not well defined; paul: wants to take closer look.
	10. erik: embarrassing: "subtraction" defn may be ambiguous; will
		look closer.
	11. erik: fcns convert things to strings: output from these fcns
		may not be definitive; need a canonical form; not sure how
		big a concern it is; hal: should suggest not converting
		to string then comparing the results; erik: either say
		it can't be relied on, or do what xml schema says;
		erik: for those types where well-defined conversions
		exist use those, ow make stmt indicating situation.

	x. tony: believes text and example are in conflict in sec 7.7.
		hal: msg 8 in April; tony: in sec mismatch
		see post. paul: target is conjunctive list of disjunctive
		lists, so should study more to determine what is correct.
		hal: discussion should go on list; rich: need to look
		further before deciding what is default action based
		on proposal.

	-. jan's latest missing attr issue will be put in post-3.0 bin

  remon: http://lists.oasis-open.org/archives/xacml/201104/msg00006.html
  greg: original posting of profile: March 23, 2011:
  original (Paul from november 2010):

  greg: paul's email query for attr predicate, agrees w comments, if
	can't get attr from pip, will do attr pred query; at that point
	not clear what apply stmt to use?
	paul: there is issue w how pdp is impl'd, no profile to be defined,
	possibly a small profile saying this is impl option. greg:
	how high up in tree to go is ambiguous.

  hal: time has expired for meeting;
  hal: will try to get draft for cd vote for apr 21, then go to weekly
	mtgs for pub rev etc.
