Other Deliverables

The XML Core Working Group is responsible for maintaining the test suites associated with the specifications listed in the Scope section and providing careful updates as warranted.

This WG handles core XML architectural issues and as such may deal from time to time with several other specifications beyond those specifically listed in the scope.

The XML Core Working Group had previously published C14N 1.1 which is now a deliverable of the XML Security WG. Due to patent policy commitments, any new edition of C14N 1.1 would need to be jointly developed by the XML Security WG and the XML Core WG. The XML Security WG is expected to do the development work, and the XML Core WG would review it before publication.
