[fullsome description of N3 and SPARQL path syntax removed]

Thanks Andy, that made it a lot clearer.

Limiting property paths to P position, and expressions to O seems like  
it would work, as long as PPs don't allow whitespace. Is this  
currently enforced?

A syntax for PPs, which required (a future) expression syntax to use  
delimiters seems a little anti-social.

Yes, exactly.
