Interesting.

I think this approach is entirely consistent with what we have been trying 
to do for RDF.  One might go on to talk about visualization of RDF 
definitions, e.g. as a graph (as is commonly offered), in which the visual 
affect of traversal might be similar to that for WebCGM or SVG.  (I'm not 
suggesting you should say that, just pointing out that it seems consistent.)

There's an attempt to describe fragments in RDF at:
