Description Tim Mills 2015-09-29 16:05:55 UTC 
In the XQuery family of documents, comparison of items is often defined with reference to fn:deep-equal.  In fn:distinct-values, this is not the case.  

I believe that the extensive set of rules in distinct-values follow those of deep-equal, and the text might be simplified by referencing deep-equal.
Comment 1 Michael Kay 2015-09-29 18:58:08 UTC 
I agree. I was going to suggest that the same observation also applies to fn:index-of, but it seems that this differs in that NaN != NaN.
Comment 2 Michael Kay 2015-10-06 17:14:24 UTC 
The WG agreed to make this change, and it has been made.
