No, I don't say they are, I say that I always thought of them as such. 
You may not share this point of view.

The distinction only exists if one ignores XSD entailment, which at 
least some SPARQL engines do.  Otherwise, the semantics makes no 
distinction between a literal of type xs:string and a plain literal with 
no lang tag (cf Peter's email) so I have no link to back me up.

I don't want xs:string to be marked as archaic because if it is, then it 
means that I am not welcome to write something like:


:passportNumber  rdfs:range  xs:string .


Still, I am in favour of simplifying things, so instead of doing 
nothing, I would rather have plain literals without language tag removed 
altogether and replaced by typed literals of type xs:string.
