In VOSpace 2.0, I have assumed that the <uws:parameters> define the job since there is no initial POST - what is posted is the full XML representation of the Job resource, e.g.:

OK - now I see what you are doing - As far as the UWS specification goes, I think that the initial POST can be anything, and I guess that the using the a document conforming to the uws:job schema is ok, though I think a rather confusing, and possibly limiting choice. I would personally use a specific vospace schema that does what you want directly as the JDL, rather than trying to squeeze this into the allowable spaces in the UWS job description (and incidentally the schema "any" definition in the UWS schema does mean that any <vos:transfer> needs to be in a <uws:jobInfo> element).
