Gaff,
I can't really answer questions about how you should model something
(since I don't really know what goal you are trying to achieve and don't
have the time). Typically its a good idea to define a global element for
anything you wish to serialize at the root of a document. If you
already know the model you want, but don't know how to write it as a
schema, you might want to try creating the Ecore model directly,
creating a GenModel for it, and then exporting the corresponding
schema. This demo might help:

You should try to ask more specific questions because open ended ones
that require a long story are much less likely to get the kind of
information you are looking for...
