xsd:anyURI and xsd:string are distinct primitive datatypes according
to "XSD 1.1. Part 2: Datatypes" < http://www.w3.org/TR/xmlschema11-2/>
the RDF 1.1 Semantics document is referring to.
have the same /lexcial representation/ but are not a priori the same
thing. Of course applications can take other equivalences into account,
some may identify relative and absolute URIs (certainly this breaks
their non-equivalence as strings) others may cast strings conforming
to IRI constraint patterns to anyURI ...
