That's true - hadn't thought about it in that light. Luckily, the RDF
toolkit I'm using supports returning bindings by column number and not just
binding name. I fear that leaving it an open question could cause some
implementation issues, but I may be paranoid.

Also - didn't mean to criticize the manual in the first one, just pointing
out an omission. I hope that after implementing the current spec, we'll be
able to find some areas in the specification *and* the manual that we can
help to improve. There are about 6 people working on some projects over
here at Olin that are related to RDF at the moment, all of which would
benefit from having a fresnel-like language to represent the data with.

Thanks!
