OK. I want to keep the signature field required, though, so how about:

signature: digital signature over a protocol buffer serialized variation of
the SignedPaymentRequest message where signature is a zero-byte array and
fields are serialized in numerical order (all current protocol buffer
implementations serialize fields in numerical order), using the public key
in pki_data.
