Another thing to consider, or be aware of, (at least for XML-based resource formats), is this recent work by W3C XML Core WG titled "Associating Schemas with XML documents 1.0" http://www.w3.org/TR/xml-model/
We'd need to obviously still come up with something for non-XML based formats. So I'd still recommend a unique property for this.
