asn1 out of standards ?

Hi, I hope that I am addressing the correct mailing list. Where can I get the asn1 definitions related to the several Hxyz standards. Do I have to copy them out of the standard, or are there files / documents dedicated to the asn1 definitions? thank you very much, michael stini ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For help on this mail list, send "HELP ITU-SG16" in a message to listserv@mailbag.intel.com
