There is a discussion about clarifying how BIP70 signs payment requests
here:
https://github.com/bitcoin/bips/pull/41
The issue is what to do with the signature field before signing. The code
Mike and I initially wrote does this:
request.set_signature(string(""));
(sets signature to the empty string)
I think that is a mistake; it should be:
request.clear_signature();
(clears signature field, so it is not serialized at all).
So: if you are implementing, or have implemented, the payment protocol,
please chime in. I'd like to change the spec and the reference
implementation NOW, while BIP70 is still a 'Draft'.
Because this type of "hey, I'm implementing your standard and it doesn't
work the way I think it should" mistake is exactly why BIPs take a while
before being declared 'Final.'

Who cares what it is? Setting to an empty byte array is fine, IMO. The
payment protocol is already rolling out. It's implemented in several
wallets, BitPay implements it, Coinbase is implementing it, etc.
-100000 for changing such a basic thing at this point. It'd cause chaos for
the early adopters, punishing them instead of rewarding them. It'd
seriously hurt adoption of the payment protocol when it's at its most
vulnerable. We should mark BIP 70 as accepted and be done with it.

Agreed with Mike. It doesn't really matter what the signature field is
set to. Changing the standard now is too hard with too little benefit.

We have BIP70 already in use (over a hundred paid requests).
Could you elaborate on why this needs changing?

Consensus is the spec should be clarified to match current behavior, so it won't change.
