Do you have an example of RESTful SOAP? I think SOAP's lack of situational HTTP method adoption (i.e. it uses GET or POST for everything, vs DELETE/PUT/etc. when appropriate), and the fact that it wraps another envelope around an already available HTTP envelope makes is hard to deem any SOAP implementation as RESTful. I'm not trying to prove you wrong, I'd just like to see an example (a quick google search yielded nothing for me).

REST was initially described in the context of HTTP, but is not limited to that protocol. You could write a RESTful SAML in SOAP in JSON API, if you desired.

Fox Sports has a pretty restful XML API. I can't remember if it's SOAP specifically, though.
