Re: [xacml] New Issue#83: CORE ERRATA: error in 7.15.3 Missing attributes http://lists.oasis-open.org/archives/xacml/200707/msg00001.html http://lists.oasis-open.org/archives/xacml/200706/msg00028.html STATUS: XACML 2.0 errata updated 5 July 2007 and XACML 3.0 WD3 include fix Two different issues: non-normative table that explains how indeterminate arises, and whether some change is required in core. Eric - issue is what status code should be retuned when policy returns indeterminate. Errata has captured this issue so that there is no ambiguity. E-mail thread captures the required table - we will resolve where it will live at some other time (new proposed policy guide).
