TITLE, ABSTRACT AND STATUS SECTIONS

Canonical XML 1.1
=================

Abstract
--------
Canonical XML 1.1 is a revision to Canonical XML 1.0 to address issues 
raised while producing the xml:id specification.

Any XML document is part of a set of XML documents that are logically 
equivalent within an application context, but which vary in physical 
representation based on syntactic changes permitted by XML 1.0 [XML] 
and Namespaces in XML [Names]. This specification describes a method 
for generating a physical representation, the canonical form, of an 
XML document that accounts for the permissible changes. Except for 
limitations regarding a few unusual cases, if two documents have the 
same canonical form, then the two documents are logically equivalent 
within the given application context. Note that two documents may have 
differing canonical forms yet still be equivalent in a given context 
based on application-specific equivalence rules for which no generalized
XML specification could account.

Known Issues with Canonical XML 1.0 (C14N/1.0)
==============================================

Abstract
--------
This technical note addresses some of the issues related to 
inheritance of the XML attributes xml:base and xml:id and the 
W3C Recommendation for Canonical XML Version 1.0 [C14N10] (Errata). 
Shortcomings of C14N/1.0 are noted out and the use of a new 
C14N/1.1 recommendation with the XML Digital Signature 1.0 
Recommendation [XMLDSIG] is discussed.

This is the W3C Working Group Note of "Known Issues with 
Canonical XML 1.0 (C14N/1.0)", produced by the XML Core 
Working Group, as part of the XML Activity. A companion note, 
"XML Digital Signatures in the 2006 XML Environment" [XMLDSIG2006], 
describes in further detail how a revised canonicalization 
algorithm (C14N/1.1 or other) may be used with the current 
XML-SIG/1.0 Specification.

Using XML Digital Signatures in the 2006 XML Environment
========================================================

Abstract
--------
This technical note describes how to use the XML Digital 
Signature Recommendation [XMLDSIG] in a way consistent with 
the present (fall 2006) XML environment. In particular, this 
note takes into account the recent xml:id Version 1.0 [XMLID] 
Recommendation, and work in progress towards a Canonical XML 
Version 1.1 [C14N11] Recommendation.

This note suggests constraints on the use of XML Signature, 
and relies on extension points present in the XML Digital 
Signature Recommendation. This note does not override any 
aspect of that Recommendation.
