W3C issues' exclusive Canonical XML' as a Recommendation. (Internet Products).

The World Wide Web Consortium (W3C (World Wide Web Consortium, An international industry consortium founded in 1994 by Tim Berners-Lee to develop standards for the Web. It is hosted in the U.S. by the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT ( ) has released Exclusive XML XML
 in full Extensible Markup Language.

Markup language developed to be a simplified and more structural version of SGML. It incorporates features of HTML (e.g., hypertext linking), but is designed to overcome some of HTML's limitations.
 Canonicalization as a W3C Recommendation A W3C Recommendation is the final stage of a ratification process of the World Wide Web Consortium (W3C) working group concerning the standard. It is the equivalent of a published standard in many other industries. . This specification augments the previous Canonical XML According to the W3C, if two XML documents have the same canonical form, then the two documents are logically equivalent within the given application context (except for limitations regarding a few unusual cases).

 Recommendation to better enable a portion of an XML document (i.e., a fragment) to be as portable as possible while preserving the digital signature. It works in combination with XML Signatures, the W3C Recommendation produced jointly by W3C and the IETF See Internet Engineering Task Force.

IETF - Internet Engineering Task Force
 in February, representing cross-industry agreement on an XML-based language for digital signatures.


A W3C Recommendation indicates that a specification is stable, contributes to Web interoperability Web interoperability means producing web pages viewable in standard compatible web browsers, various operating systems such as Windows, Macintosh and Linux and devices such as PC, PDA and mobile phone based on the latest web standards. , and has been reviewed by the W3C Membership, who are in favor of supporting its adoption by academic, industry, and research communities.

Exclusive XML Canonicalization Makes XML Signatures Work with Complex Applications, Web Services Digital signatures provide integrity, signature assurance and non-repudiatability over Web data. Such features are especially important for documents that represent commitments such as contracts, price lists, and manifests.

XML Signatures have the potential to provide reliable XML-based signature technology, and are considered a mandatory component of many models for Web Services. However, various processors may introduce incidental changes into a document over the course of its processing. The process of canonicalization removes these incidental changes. Additionally, in some cases, particularly for signed XML in protocol applications (that is, ones that use SOAP 1.2, HTTP/l.1, or others) there is a need to canonicalize a subdocument in such a way that it is substantially independent of its XML context.
