Title - Note on using xml:id should reference Canonical XML 1.1 and XML Signature, Second Edition

Description/Justification

Currently section 4.2, Policy Identification contains a note that use of Canonical XML 1.0 with xml:id is not appropriate. This is correct.

It has an additional Note that Canonical XML 1.1 is intended to address this and that the XML Security Specifications Maintenance WG has been chartered to investigate. This is no longer accurate since Canonical XML 11 has been released as a Recommendation as has XML Signature (Second Edition).

Target - framework

Proposal

Create Proposed Errata against Framework document.

(Part 1) Replace the following text in section 4.2, Policy Identification:
---
Note:
Canonical XML 1.1 [C14N11] is intended to address the issues that occur with Canonical XML 1.0 with regards to xml:id. The W3C XML Security Specifications Maintenance WG has been chartered to address how to integrate Canonical XML 1.1 with XML Security, including XML Signature [SecSpecMaintWG] (See http://www.w3.org/2007/xmlsec/.)
---
With the following text:
---
Note that is is acceptable to sign a policy expression identified using xml:id with XML SIgnature (Second Edition) [XML-Signature-2ndEdition] and Canonical XML 1.1 [C14N11], as these recommendations  address issues related to the use of xml:id and xml:base.
---
(Part 2)
Update the reference to C14N11 in Appendix B.2.

Replace the following:
