Within the encoded data, the optional bit being set means an OPTIONAL value is encoded, while the optional bit being off means an OPTIONAL value is not encoded. If the receiving side receives an OPTIONAL value, the DEFAULT value is no longer material; if the receiving side does not receive an OPTIONAL value, the DEFAULT value would be used, in which case it would be the receiving side that knows (via the ASN.1) which value it should be. What additional information do you believe needs to be relayed via a default status bit? I think none. ===================================================================== Conrad Sigona Toll Free : 1-888-OSS-ASN1 OSS Nokalva Voice Mail : 1-732-302-9669 x400 [EMAIL PROTECTED] Fax : 1-419-831-5035 http://www.oss.com My direct line : 1-315-845-1773
