Body
ITU-T SG17, Security, thanks IETF Security Area for the liaison response about
our draft Recommendation ITU-T X.cms. The main reason for the development of
X.cms is to have an ITU-T Recommendation containing all the ASN.1 modules which
are needed to implement Cryptographic Message Syntax with no obsolete ASN.1
features like “ANY DEFINED BY”. For ITU-T to make references, we need CMS with
ASN.1 specifications conform to the in force Edition of Rec. ITU-T X.680 series.

We decided to postpone the Consent of draft Recommendation ITU-T X.cms to have
the time to investigate the possibility to have an updated IETF RFC that
fulfils our requirements. Our ASN.1 experts offer to participate in the work on
producing that IETF RFC.
