Hello,

for your information, we're working on a charter for a W3C Working
Group that would have the task to specifically sort out the xml:id
mess in XML Signature (by making C14N 1.1 the mandatory to implement
algorithm, and essentially making the changes described in the
dsig-usage note), and to fix the Decryption transform for XML
Signature by making similar changes.

The expectation is that this charter would limit the
conformance-affecting changes that the group can make to those that
are demonstrated to be necessary to sort out the immediate problem.

To make the work less dull, the group will also have the mandate to
write a draft charter for broader follow-up work, and to identify
issues that need to be addressed.

We intend to have the version of XML Signature and Processing that
this group would produce submitted to the IETF for publication as an
RFC; the mechanics of that are presently being discussed.

Feed-back on the overall approach would be most welcome.

Regards,
-- 
Thomas Roessler, W3C   <tlr@w3.org>
