Review. Error - Section 10.1 ORDER BY examples dont match grammar

Review of http://www.w3.org/2001/sw/DataAccess/rq23/ v1.379

Section 10.1 on ORDER BY has:

SELECT ?name
WHERE { ?x foaf:name ?name ; :empId ?emp }
ORDER BY DESC[?emp]

But grammar has:

[14] OrderClause ::= 'ORDER' 'BY' ( OrderCondition )+

Suggestion to fix: replace []s with ()s in ORDER BY examples.
