So, assigning the contents of a file to the body attribute of an IBody has
the side-effect of initialising the context of the multi adapter from obj,
environ -> IBody with the XML contents of that file?
I'm guessing I can bundle some of this functionality into a more general
interface (e.g. "addWorkflowFromXMLDefinition()") and use it in my setup
methods. At least for workflows and FTIs, this'd be great.
