The W3C XML Security Specifications Maintenance Working Group
has posted the Proposed Edited Recommendation of
XML Signature Syntax and Processing (Second Edition)
"This Proposed Second Edition of XML Signature Syntax and
Processing adds Canonical XML 1.1 as a required
canonicalization algorithm and recommends its use for inclusive
canonicalization. This version of Canonical XML enables use of
xml:id
and xml:base
Recommendations
with XML Signature and also enables other possible future
attributes in the XML namespace. Additional minor changes,
including the incorporation of known errata, are documented in
Changes in XML Signature Syntax and Processing
(Second Edition)." I have to read through the detailed changes, but at first glance this looks like a reasonable adjustment that doesn't break any existing code.
