Oh, you're right, the multipart style is missing here, and it says:

    The localPart of the element's QName MUST be the same as the
    Interface Operation component's name.

I am actually unsure about the motivation and need for this
requirement of the style.

Well, actually, you could have only 2 operations, and 2 bindings of
those, one for GET and one for POST, supposing that query[1-4] are the
same input message.
