(Thanks, Sandro---I had let the RDF/XML serialization cloud my thinking, and didn't realize that this was available in the RDF model.) I think that the lack of literals in rdf:List in an RDF/XML serialization will be irrelevant, one way or another; I don't think that should affect the analysis. I'd be interested in knowing the answer to this question concerning literals in lists using SPARQL, as I don't (yet) use SPARQL. Garret
