Yes, if one assumes that entailment is made relative to a datatype 
map which recognizes xsd:string.  In fact it is a datatype clash.  A 
string is simply a string: it has no associated language.  "Carpe 
diem"@en denotes a pair, not a string.

You could have made the range be rdf:Literal; that would have been OK.
