[Enigmail] official protocol for external helper program

Is there any chance for enigmail to support some official protocol for
messages signing/encrypting and verification of message signature?

I have asked for support of "X-PGP-Sig:" but I will be happy to use more
general solution.
[e.g. execute external program, feed it XML via its stdin, read XML it
produces via stdout and error/report via stderr.
