"The deployment of XML Base is through normative reference by new specifications, for example XLink and the XML Infoset. Applications and specifications built upon these new technologies will natively support XML Base." [1] XML Information Set specification has a normative dependency on XML Base [2]. Any specification built upon XML Information Set will natively support XML Base. Web Services Policy is built upon XML Information Set. So, it doesn't hurt to explicitly call out the support for XML Base.

The following is a list of proposed changes to resolve issue 4039:

Framework:

a)	Add a new section 4.6

4.6 Use of IRIs in Policy Expressions

Policy expressions use IRIs for some identifiers. This document does not define a base URI but relies on the mechanisms defined in XML Base [XML Base] and RFC 3987 [RFC 3987] for establishing a base URI against which relative IRIs can be made absolute.

b)	Updates to the application/wspolicy+xml Media Type

s/Base URI: 
As specified in RFC 3023, section 6.
/Base URI: 
As specified in RFC 3023, section 6. Also see section 4.6 Use of IRIs in Policy Expressions in this document and section 3.5  Use of IRIs in Policy Attachment in the Web Services Policy 1.5 - Attachment.
/

c)	Add a normative reference to XML Base.

Attachment:

d)	Add a new section 3.5

3.5 Use of IRIs in Policy Attachment

Policy attachment mechanisms use IRIs for some identifiers. This document does not define a base URI but relies on the mechanisms defined in XML Base [XML Base] and RFC 3987 [RFC 3987] for establishing a base URI against which relative IRIs can be made absolute.

e)	Add a normative reference to XML Base.

General:

f)	XML Base Second Edition

This month, the XML Core WG plans to advance [3] the XML Base Second Edition draft as a Proposed Recommendation. Editors should take a tickler action to refresh the XML Base reference (Second Edition) prior to CR publication.

Subject: [NEW ISSUE] 4039 WS-Policy does not define its relationship to XML Base


http://www.w3.org/Bugs/Public/show_bug.cgi?id=4039 

Title: WS-Policy does not define its relationship to XML Base [1]

Description:

WS-Policy does not define its relationship to XML Base [1]

Justification:

The XML Base spec says:
       The deployment of XML Base is through normative reference by new
specifications, for example XLink 
       and the XML Infoset. Applications and specifications built upon these
new technologies will natively support 
       XML Base. The behavior of xml:base attributes in applications based on
specifications that do not have 
       direct or indirect normative reference to XML Base is undefined. 

Unspecifying the relationship to XML Base will likely lead to interoperability
problems, since by definition, behavior is undefined.

Proposal:
TBD, but roughly treat along the lines of how SOAP1.2 has handled it [2]
