W3C Invites Implementer Feedback on XML Security 2.0 Specifications

The XML Security Working Group invites implementation of three Candidate Recommendations: XML Signature Syntax and Processing Version 2.0, Canonical XML Version 2.0, and XML Signature Streaming Profile of XPath 1.0. XML Signatures provide integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere. The XML Security 2.0 specifications are designed to update the XML Signature and Canonical XML specifications to improve performance, streaming support, robustness, and reduced attack surface.

The Working Group has also published a W3C Note: XML Security RELAX NG Schemas, a document that provides RELAX NG schemas corresponding to the normative XSD schemas for XML Signature 1.1, XML Encryption 1.1, and related specifications.

To address patent disclosures related to the XML Signature 1.1 and XML Encryption 1.1 specifications, W3C has chartered a Patent Advisory Group. Concerns related to XML Signature 1.1 may also apply to XML Signature 2.0.
