Yes, I think I understand that. I am not convinced that such should be part of the core signature. It's more of the form of a Manifest of the document and some assertions about that document that allow you to do what you want to do. > As for whether document closure overcomplicates things, we are > talking about the same group of people that intellectually grasp the fact that No, I have not been reffering to myself :-) I am talking about all those who are not. And in the light of digital signature laws, I am always having in mind the What-You-See-Is-What-You-Sign principle as well, and that users should be able to understand what they sign. And such a feature doesn't fit in. These ideas, while intellectually interesting, seem to be a little contradictory to WYSIWYS in the general case. I understand, that signing (ABCDE - C) might even be "explainable" to the user, but given that functionality, I have no doubt that something like: "I sign ABDE, but between B and D there could be a C, or an F - but only if there is also a G between D and E" or something even more complicated is possible. This results in equality to "fine print in contract illegible by the consumer without magnifying class". I do understand that we easily can limit signatures to a simple form for anything related to electronic signature laws. And there even might be applications that want to make use of that. But why not avoiding this alltogether and move it up one floor? Seems cleaner to me. Peter
