Hmmm.... Then TDL is invidious to its very core. The whole point of TDL is that a given literal, e.g. "10" can represent different values in different datatype contexts. In the context of xsd:integer it is 10. In the context of xsd:string it is "10". In the context of e.g. ex:binaryInteger it is 2. Etc. etc. A literal in and of itself means nothing. It must have context for its interpretation as a value. A TDL pairing is a "literal-in-context" which denotes a value. Thus, so long as we are cursed to have lexical forms in the graph, we will have some degree of untidyness -- either untidy literals or untidy bNodes with tidy literals hanging off of them. Right?
