Subject: [xacml-comment] A comment on Section 7.3
Hi, Section 7.3 says that The target value SHALL be "Match" if the subjects, resource and action specified in the request context are all present in (i.e., within the scope of) the target. This sentence is unclear to me because the meaning of "present" is unclear to me. Why doesn't Section 7.3 mention MatchId? I think Section 7.3 should reference A.12, where I can find the detailed semantics of MatchId. It seems to me that the term "present" is used in three places (ignoring the "present" function), 1) Section 3.3.1.1 Rule target The meaning of "present" used here is also unclear to me, but I can accept this situation because Section 3 is non-normative. 2)Section 5.27, 5.28, 5.29 (Resource, Action, Environment Attr Designator) There is clear definitions of "present" from the attribute designator perspective. (I think these definitions have nothing to do with MatchId attributes used in <Target>) 3)Section 7.3 Is the term "present" used in Section 7.3 the same as the ones defined in Section 5.27, 5.28, 5.29???
