Hi Monica,

>is missing in the Primer.

My recollection is .. there is a reason why examples are missing. WG's
plan of record on issue 3560 is:

"RESOLUTION: 3560 closed with the proposal in Umit's proposal in
http://lists.w3.org/Archives/Public/public-ws-policy/2006Jul/0099.html
as amended by
http://lists.w3.org/Archives/Public/public-ws-policy/2006Aug/0074.html
and
http://lists.w3.org/Archives/Public/public-ws-policy/2006Aug/0099.html"
[1].

The second amendment [2] is to remove the proposed example.

Subject: New Issue 4069: Updating References for Use of xml:id


see: http://www.w3.org/Bugs/Public/show_bug.cgi?id=4069

=============
Title: Updating References for Use of xml:id
Target: Primer, Framework
Description and Justification:
Issue #3752 and #3560 [1] introduced and clarified the use of xml:id. 
However, a few more areas exist where xml:id is available for use. This 
should be clarified in the Framework and Primer documents. Currently, no

example using xml:id exists in the Framework and its use is missing in 
the Primer. With the addition of xml:id, its use should be described and

exemplified.

Proposal:
1. Framework, Section 4.2 Policy Identification
[amend to end of this section]

The following example illustrates how to associate a policy expression 
with the IRI-reference |"#P1"| using xml:id:

  (01) <wsp:Policy
         xml:id="P1"
         xmlns:wsp="http://www.w3.org/@@@@/@@/ws-policy"
         xmlns:xml="|http://www.w3.org/XML/1998/namespace|" >
  (02)   <!-- Details omitted for readability -->
  (03) </wsp:Policy>

2. Primer
Section 2.8 Referencing Policy Expressions
a. Change from:
  A policy expression may be identified by an IRI and referenced for
  re-use as a standalone policy or within another policy expression.
  There are two mechanisms to identify a policy expression: the wsu:Id
  and Name attributes. A PolicyReference element can be used to
  reference a policy expression identified using either of these
  mechanisms.

Change to:
  A policy expression may be identified by an IRI and referenced for
  re-use as a standalone policy or within another policy expression.
  There are three mechanisms to identify a policy expression: the
  wsu:Id, xml:id and Name attributes. A PolicyReference element can be
  used to reference a policy expression identified using either of
  these mechanisms.

b. Change from: Example 2-14

Change to:
[new paragraph under Example 2-14]
In the examples 2-12, 2-13, and 2-14 Contoso could have used either the 
xml:id or wsu:Id.

Note: There are no changes to Example 2-14 or the existing paragraph 
that follows: The |Name| attribute is an alternate mechanism to identify

a policy expression....

Section 3.2 Normal Form for Policy Expressions (now Section 3.6)
[Note: As Issue 3965 was accepted, this text would be updated in new 
Section 3.6, Primer.]

Change from:
  If the referenced policy expression is in the same XML document as
  the reference, then the policy expression should be identified using
  the |wsu:Id| (XML ID) attribute and referenced using an IRI
  reference to this XML ID value.

Change to:
  If the referenced policy expression is in the same XML document as
  the reference, then the policy expression should be identified using
  the |wsu:Id|xml:id (XML ID) attribute and referenced using an IRI
  reference to this XML ID value.

  Reason: This is really clean up from Issue 3752,
  http://www.w3.org/Bugs/Public/show_bug.cgi?id=3752. This is also
  consistent with text in Section 4.3.4 Policy References in the
  Framework ("This attribute references a policy expression by an IRI.
  For a policy expression within the same XML Document, the reference
  SHOULD be an IRI-reference to a policy expression identified by an
  |ID|.").

Note: No changes are proposed for Guidelines, Section 5.1 although they 
may be considered in the future.
