I read the latest draft-barnes-acme-03.txt and have a question:

Is there an option for the ACME server to "send" or provide the ACME client
a file, e.g. a PDF document that contains an invoice, contract, form etc. I
think this is not possible with the current draft ACME spec but I want to be
sure that I have not overseen that option.

I understand that the ACME server could email such a file/document to the
email address that is associated with the registration object, but that
seems out of band to the ACME protocol and I'd like to avoid OoB communication.

Any insight is much appreciated, thanks,
