The intent is that they should be normalized (again) before comparison, unless you're completely sure they already are. But giving this a MUST is tough, because it's not actually done currently (except for IDNs, but in that case also only for IDN 2003 and/or TR 46, not for pure IDN 2008). >> In my opinion, RDF literals fit the definition of "identifiers". > > I can't imagine why you think so. RDF literals are strings (except > when they are typed as numbers, dates, etc.) Correct. I think Addison meant RDF URIs, i.e. the things that are used to identify resources. Regards, Martin.
