Hello! I'd like to have a clarification of the signature subpacket 5.2.3.22. Signer's User ID (String) This subpacket allows a keyholder to state which User ID is responsible for the signing. Many keyholders use a single key for different purposes, such as business communications as well as personal communications. This subpacket allows such a keyholder to state which of their roles is making a signature. This subpacket is not appropriate to use to refer to a User Attribute packet. It is not clear to me whether the string should be a verbatim copy of the content of a User ID packet or some other information. The second paragraph could be viewed as a hint for a verbatim copy. OTOH, for applications it makes more sense to have just the vanilla mail address (mailbox@domain) here. This would make it easier to compare a mail's From address to the actual signature. I don't care much about this but given that such a subpacket has been defined but is not widely used - if at all - we might want to define it in a stricter way. Shalom-Salam, Werner
