My concern here is that we won't be able to go from XML to N3 or RDF/XML 
representation without loosing information, which seems to give a higher 
status to the XML representation.  I think that, although it could be 
cumbersome in some cases, we can stick to RDF statements by referring to 
resources, such SVG or a SVG fragments, by their URI instead of "inlining" 
them in annotations.
