Both. The binding is not specific to POST or GET, it requires both as a
method to transmit or receive an artifact. This was copied from ID-FF,
although nobody seemed to know that it was there. The purpose is to allow
GET vs. POST to be decided as a deployment issue independent of the
deployment decision of whether to use artifact or not. The only reason
Redirect and POST are separate bindings is that they're such different
encodings.
