Re: Proposal

These are all good questions Frank, and are valid regardless of whether
we stick with the present solution or go with the latest proposal.

They all have to do with how the XML fragment in the RDF/XML is
mapped to a string (either lexical form or plain literal) in the graph,
and that mapping will likely be the same no matter which solution is
chosen.
