IRI references rewording

I have changed the text in the gramamr section for IRI references to 
explicitly say which rules are required to generated valid IRIs

"""
IRI References

SPARQL is defined in terms of absolute IRIs (this includes the fragment 
identifier). IRI references formed by rule Q_IRI_REF and by rule QName (after 
prefix expansion) must be valid according to RFC 3987 [RFC3987] and RFC 3986 
[RFC3986]. They are converted to absolute IRIs according to RFC 3987 and RFC 
3986, using the base IRI defined by the BASE clause if present in the query.
