aha. so, why is this not documented at librdf_model_context_add_statement?
and why are duplicate statements allowed in contexts, but not (directly)
in models? that seems inconsistent to me.
why would anybody want duplicate statements?
also, i have just checked Sesame 2.0 (openrdf.org), which also has
contexts, and does seem to eliminate duplicate statements added to contexts.
i would welcome a bit of consistency across RDF repository
implementations, given that i am currently implementing an abstraction
layer for them...
