No but intermediate hop-by-hop HTTP agents have no way of knowing.

That is exactly what we should do.  We just disagree that 500 is a valid
status code to contain application data.

If a SOAP target wants a digitally signed message, and doesn't get it,
should it return 401, or should it leave that to the HTTP layer in case
the POST requires a basic auth?

If doing SOAP over email, a fault can only be returned by sending a
reply message, not by responding with a 451 status and using
continuation lines.  Right?

Once you start to "tightly integrate" SOAP messaging semantics with the
underlying transport, all sorts of nasty corner cases come up, like the
two I just mentioned.  That's why it's much simpler and much more clear
to think of it as tunneling.
