FW: describing a service that returns an image/jpg (for example)

Thanks for your comment.  The WS Description Working Group tracked this
as a Last Call comment LC360 [1].  The WG was unable to reach consensus
to add this functionality at this late date, and closed the issue with
no action.

As we plan to go to CR shortly, if we don't hear from you within 10
days, we will assume this satisfies your concern.

> When we document the "one-binary-thing" style we say that that if that
> style is used then the output serialization must be set to something
