Yes, it is required. OpenPGP applications have to know where the signed
data starts and where it ends. There is no garuntee that the entire
message body will be signed. For instance, suppose I forward your message
to someone else, or I send you an archived copy of a signed message. Or
suppose and email app sends the entire message, mail headers and all, to
an OpenPGP app for processing. In these cases, the OpenPGP data needs to
be marked.
