p.s. :
Just got clarification on that from the SPARQL crew:
it is correct there and equivalent to the N3 and Turtle
grammars, I missed that IRIref != IRI_Ref, i.e. the rule:

    IRIref ::= IRI_REF | PrefixedName

was missing above, again 'PrefixedName' is what we refer to as CURIE.

So, all three languages SPARQL, N3 and Turtle agree on the use of '^^'.
