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.
