The XQuery 1.0 Candidate Recommendation is quite clear about this (http://www.w3.org/TR/xquery/, Section 3.8.3): 1. If V1 is greater-than V2: If the orderspec specifies descending, then T1 precedes T2 in the tuple stream; otherwise, T2 precedes T1 in the tuple stream. So, everything but `descending' is to be interpreted as `ascending', including the absence of an explicit modifier.
