What definition or statement does it refer to and/or what defines whether the ordering mode is ordered or not for the selection in the expression? Filed under XP31 so that it gets on the agenda, but applies equally to both XP30 and XP31. 122031 1 jonathan.robie 2015-07-14 15:50:40 +0000 I will remove this text from XPath 3.1. Ordering mode is defined only for XQuery: [Definition: Ordering mode. Ordering mode, which has the value ordered or unordered, affects the ordering of the result sequence returned by certain expressions, as discussed in 3.14 Ordered and Unordered Expressions.] Section 3.14 also appears only in XQuery. 122032 2 mike 2015-07-14 16:08:07 +0000 Rather than removing the text, you should retain the part that applies: the returned sequence preserves the orderings within and among the subsequences generated by the evaluations of E2 122033 3 jonathan.robie 2015-07-14 16:15:21 +0000 (In reply to Michael Kay from comment #2) > Rather than removing the text, you should retain the part that applies: > > the returned sequence preserves the orderings within and among the > subsequences generated by the evaluations of E2 Done.
