Subject: Re: [xacml] Minutes of 5 June 2003 Focus Group meeting
The following is a correction report sent to me personally from Jim Fuller. Simon, please include the first three errors to your list. ============ In my quest to build an xacml processor, I have a few comments typos or errata in current spec pdf ( u probabably have already caught these ) ------------------------------------------------------------------------- line 782 error with xacml:Policy endtag; xacml: xmlns is undeclared at begin element line 841 error missing end quote in attribute definition line 856-861 missing XML Schema attribute, illegal xml attribute 2 cheap points on why its important to make xacml easier to manually create - its not good enough to state that xacml is meant to be 'generated', it smacks as an excuse for the overly complicated format of attributeid values; refering back to xml 1.0; xml should be human-legible. - xml docs should be easy to create; xacml is unusually verbose, no doubt the deep thinking with policysets and the more complicated corner cases are catered for but the with the lack of editors, I have been forced to create a simplified xacml, then use the magic of xslt ...which is all very boring. ============= Michiharu Anne Anderson <Anne.Anderson@Su To: XACML TC <xacml@lists.oasis-open.org> n.com> cc: Subject: [xacml] Minutes of 5 June 2003 Focus Group meeting 2003/06/06 05:21 Please respond to Anne.Anderson Minutes of OASIS XACML Focus Group 05 June 2003 Present: Anne Anderson (scribe), Ed Coyne (SAIC, prospective), Michiharu Kudo, Simon Godik, Carlisle Adams, Steve Crocker Agenda ====== Review Errata 1. Work Item G: Environment in Target [Lower priority for today than Errata. We returned to this after discussing Errata.] Michiharu asked about why this was dropped from the 1.1 Work Item list at the last meeting. Michiharu disagrees with dropping this, but he is not clear on when something is not appropriate for 1.1 (Hal's comment about why this item should be dropped from the 1.1 Work Items). RECOMMENDATION: All requirements for including this in 1.1 have been met with the exception of agreeing on a solution by the end of June 2003. Michiharu has followed the agreed upon process of submitting a proposal by a certain date, a detailed solution by a certain date, etc. Simon has an alternative proposal/solution for this that he will submit to the e-mail list for discussion. 2. Simon still having problems downloading the specification. Michiharu has checked with OASIS webmaster, who is aware of the problem since webmaster has same problem. Michiharu will put a note on the XACML TC web site saying there may be a problem with some browsers. 3. Errata review Simon published draft-xacml-errata-02.doc attached to http://lists.oasis-open.org/archives/xacml/200306/msg00001.html - 3.12 <Status> element MAY: include action and environment attributes. RECOMMENDATION: Approve - 3.13 <Status> element MUST NOT list action or environment attributes. RECOMMENDATION: Approve - 3.14 <AttributeValue> occurrence is inconsistent. RECOMMENDATION: Approve. Also remove minOccurs="0" from line 2644 in spec to agree with schema. - 3.15 Semantics of the <<AttributeDesignator> with MustBePresent attribute set to "true" is unclear when <Attribute> does not contain <AttributeValue> **RECOMMENDATION: Needs more thought. Might approve, except change text to say "result is not an empty bag, but one empty element that is added to the resulting bag." But in the case of an empty <AttributeValue DataType="...#integer">, then the <AttributeValue> is schema-invalid. - 3.16 MustBePresent attribute semantics for the <AttributeSelector> element. RECOMMENDATION: Approve. Use status of "processing-error", not "missing-attribute" in the place where a question mark occurs. - 3.17 Unclear how to convert nodes from XPath expression into bag of attributes. **RECOMMENDATION: TBD. [XF] defines how to convert nodes into LITERAL, but the processing is very complex. Michiharu will investigate a solution. Other items in the errata list have probably already been disposed, but Simon has not yet found the relevant e-mails. - 3.7 Obligations for the policy. **RECOMMENDATION: Anne to look for e-mails where Polar? clarified to Satoshi that 7.11 refers to both <Policy> and <PolicySet> and then Satoshi said 7.11 was clear with that clarification, and so Erratum 3.7 could be dropped. - 3.9 <XPathVersion> element **RECOMMENDATION: Simon will look for discussion of this on the list. No one can remember what the disposition was. - Several new errata reported to Michiharu by Jim Fuller, but not put on xacml-comment. Michiharu will forward to xacml-comment. -- Anne H.
