The complete set of ASN.1 standards documents are available free from the
ITU-T SG17 website.  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).
