If a literal constant is just a value from {"urn:data:literal:", Unicode*} as suggested in http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Jul/0042.html, we should not need an additional identifier. > But further to 2.; while we should not give literals URI's , they are > nevertheless resources.
