Right, so this is why I think my rules are wrong, because the above
should, in my mind, yield:

<#b> a:b _:span0

(where _:span0 can be the subject of other triples nested within the SPAN).

Yeah, I definitely think that's wrong. So my rules are wrong.

Indeed, you're right.

Remember that we agreed that we would not try to represent all of RDF in
RDFa, and especially we would not try to represent everything in nice
syntactic sugar form... we would only do well motivated use cases.

I am *very* wary of introducing "_:" for this limited use case,
especially since I haven't seen strong motivating examples that couldn't
be expressed in other ways (slightly clunkier, but not requiring new
syntax.)

So, this requires more thought. I'm really not sold on "_:"
