Keep in mind the distincion between a document and a (named) graph. A document is a resource on the Internet with an address. You can reason about this resource using RDF triples. To any subset of triples you can attach a new address: the name of a graph. This name can again be used reason about. But, all by all, this technique stays problematic. You still need to enumerate all the triples you would like to name. On an Internet wide-scale this can be inpractical. Yes, by using these RDF documents as normal resources.

This really helps explain the problem and some possible solutions. (And explains why reification might be both important and troublesome in RDF!) Extending the RDF/XML with the rdf:graph attribute seems useful--but what if you have multiple 'levels' of documents (e.g. documents in RDF which themselves discuss documents in RDF)? Thanks!
