The XML Core Working Group is also chartered to discuss issues related to the maintenance of other XML-related specifications that may be raised by the community


The Working Group has current plans to:

Note that the development of new W3C Recommendations not listed in this document would require a new charter revision.

In addition, the XML Core Working Group is chartered to decide whether to develop a MicroXML Recommendation based on the work of the MicroXML Community Group. If it decides to go ahead with MicroXML work a W3C Advisory Committee Review would bee needed to confirm the necessary change to this charter.

Other Deliverables

The XML Core Working Group will maintain and/or develop test suites for each specification as needed.

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 will review it before publication.
