Yes, I know, there are good cases for both separate signatures and for signing over previous signatures. We decided to exclude all signatures two con calls ago when we could not figure out how to add a signature without breaking a previous signature (how do you know which signature to process first and then you must exclude the later signatures when processing the earlier ones). We decided NOT to discuss, in the spec, the use of multiple signatures. As with all things in this group, nothing is final ;-^. Regards, David Fischer Drummond Group.
