It doesn't need to understand 'data:' (by which I mean: no need for special 
interpretation of 'data:'), only that RDF literals may be re-cast as 
resources using the data: scheme.  A presented data: resource would (or 
should in my view) be treated like any other URI.

I don't think this is a new problem.  Currently "10.000" and "10.00" are 
two distinct literals.  They just happen to be equivalent under some 
interpretations.  (I'll observe that on engineering drawings they commonly 
have different interpretations.)
