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.

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

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

- 3.12 <Status> element MAY: include action and environment


- 3.13 <Status> element MUST NOT list action or environment


- 3.14 <AttributeValue> occurrence is inconsistent.

  Also remove minOccurs="0" from line 2644 in spec to agree with

- 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.
