Possible Future XML Security Specifications Work

Name of WG

XML Security Working Group

Background Material


Requirements Phase

In considering these use cases and requirements, the Working Group's attention is in particular alled to algorithmic performance and efficiency.


Specify one or more canonicalization algorithms to address the requirements agreed. At least one such algorithm should be suitable to replace Canonical XML 1.1 as a mandatory to implement canonicalization method.

Further development of XML Signature

Develop an update to the XML Signature Syntax and Processing Recommendation:

The result of this development can take the form of profile(s) or a revised specification. The Working Group is asked to consider the benefits of compatibility with the existing specification environment.

The Working Group MUST follow the versioning policy for the namespace currently used by XML Signature Syntax and Processing.

Further development of XML Encryption

Develop an update to the XML Encryption specification to ensure consistency with possible changes to the XML Signature specification, and to accommodate additional cryptographic algorithms as determined necessary.

Maintenance Work

The Working Group may only make changes of classes 1, 2, and 3 as outlined in section 7.6.2 of the Process document.


Charter for 24 months.
