BNF for EARL

Hi,

I am playing around with the idea of formalizing the EARL model in BNF and would love some feedback. Below is a very rough outline of the idea. Note that it is missing all the strings to generate the actual RDF/XML tags as well as inheritance and other RDF-specific stuff. Still, it already shows some interesting concepts about the actual model and what parsers currently need to process. Is this worth while and useful for others?
