I am asking myself whether there is an error in the SPARQL grammar for
typed RDFLiterals:
I think it's just a case of poor naming :) See below.
Now, when I look at SPARQL's grammar I find:
SPARQL: http://www.w3.org/TR/rdf-sparql-query/
RDFLiteral ::= String ( LANGTAG | ( '^^' IRIref ) )?
IRI_REF ::= '<' ([^<>"{}|^`\]-[#x00-#x20])* '>'
IRIref != IRI_REF
The relevant rule is
http://www.w3.org/TR/rdf-sparql-query/#rIRIref
which reads:
[67] IRIref ::= IRI_REF | PrefixedName
So I believe this is correct.

Note: No qnames are allowed here in the type position, although
qnames like xs:integer *are* actually used for typed literals in
the examples in the SPARQL document.
I assume this is a bug?
