Done - this text forms the IRI section in the grammar (A.1)with the addition I 
listsed the qname production to the Q_IRI_REF as well as it created IRIs as well.

"""
A.1 IRI References
Text matched by the Q_IRI_REF production and QName (after prefix expansion) 
production must be conform to the generic syntax of IRI references in section 
2.2. ABNF for IRI References and IRIs RFC3987]. For example, the Q_IRI_REF 
<abc#def> may occur in a SPARQL query string, but the Q_IRI_REF <abc##def> 
must not.
