The intent is simply to support this in the standard SOAP HTTP binding,
but we could certainly imagine alternate SOAP/HTTP bindings which might
support it as well.  You're quite right though, it would only make sense
to specify this for a binding which actually supported the feature in
question - non-HTTP bindings couldn't well do that in this case (though
they certainly could support the abstract optimization feature, or other
less-http-specific features that used XOP and MIME).
