Has the RDF* group agreed that nesting should be supported in general? I 
would consider this feature rather unnecessary. Allowing multiple levels 
of annotations (i.e. reification of reified triples) puts extra burden 
on developers who then need to create UIs and other algorithms around 
those cases. And how many of the users are going to understand these 
constructs?
