The new version [2] includes the changes John Boyer mentioned in [1]. [1] http://lists.w3.org/Archives/Public/w3c-ietf-xmldsig/2000AprJun/0246.html [2] http://www.w3.org/TR/2000/WD-xml-c14n-20000613 Abstract This specification describes a method for generating a physical representation, the canonical form, of an input XML document, that does not vary under syntactic variations of the input that are defined to be logically equivalent by the XML 1.0 Recommendation [16][XML]. If an XML document is changed by an application, but its Canonical-XML form has not changed, then the changed document and the original document are considered equivalent for the purposes of many applications. This document does not establish a method such that two XML documents are equivalent if and only if their canonical forms are identical. [16] http://www.w3.org/TR/2000/WD-xml-c14n-20000613#XML Status of this document This is the second draft of a proposal that (1) serves as an alternative approach to the Canonical XML specification using the XPath [17][XPath] data model, and (2) includes a few substantive changes that affect the canonical serialization of an XML document. It is not necessary for implementations to use XPath to generate the canonical form of an XML document. XPath simply provides a data model that is simplified compared to InfoSet, yet sufficient for the purpose of canonicalization. XPath also provides an expression syntax for describing the desired portion of a whole document. Any variances between that result from this specification's use of the XPath [18][XPath] data model and the XML Information Set [[19]InfoSet] will be reported to the XML Information Set's comments list. [17] http://www.w3.org/TR/2000/WD-xml-c14n-20000613#XPath [18] http://www.w3.org/TR/2000/WD-xml-c14n-20000613#XPath [19] http://www.w3.org/TR/2000/WD-xml-c14n-20000613#Infoset Prior versions of this document were published by the [20]XML Core Working Group (the last of which was the [21]20000119 draft), which delegated the completion of this specification to the IETF/W3C [22]XML Signature Working Group. We expect continued substantive discussion with respect to the treatment of XML namespaces, but hope to address that (any any other issues) quickly such that we can issue a second Last Call at the beginning of July 2000. [20] http://www.w3.org/XML/Activity#core-wg [21] http://www.w3.org/TR/2000/WD-xml-c14n-20000119.html [22] http://www.w3.org/Signature/ The XML Signature and XML WGs and other interested parties are invited to comment on this proposed direction, review the specification and report implementation experience. While we welcome implementation experience reports, the XML Signature Working Group will not allow early implementation to constrain its ability to make changes to this specification. Please send comments to the editors and cc: the list <[23]w3c-ietf-xmldsig@w3.org>. Publication as a Working Draft does not imply endorsement by the W3C membership or IESG. It is inappropriate to cite W3C Drafts as other than "work in progress." A list of current W3C working drafts can be found at [24]http://www.w3.org/TR/.
