The Query and XSLT Working Groups discussed this comment at a joint meeting on 
July 20, 2005. We agree that the current inconsistency in casting behavior 
between the value comparisons and general comparisons is unfortunate. However, 
several members observed that making the two kinds of comparison more 
consistent would simply push the inconsistency to another place, such as 
between comparison operators and "order by". Also, several members were 
concerned by the impact of non-transitive comparison operators on query 
rewrites and on access methods such as indexes, sort-merge joins, and hash 
joins. For these reasons, the working groups jointly decided not to change the 
XPath and XQuery specifications as suggested by this comment.

The attachment contains a set of slides used by the working groups in 
discussion of this comment.

Since you participated in the working group discussion, I am marking the 
comment as closed. If you are not satisfied with the decision of the working 
groups, you may reopen the comment.
