The URL is: http://www.itu.int/ITU-T/studygroups/com17/languages/index.html The X.680 and X.690 series of documents make up the complete ASN.1 standard. This includes X.693 (XML encoding rules) and X.694 (Mapping W3C XML schema definitions into ASN.1). ---------------------------------------------------------------------------- Paul E.
