Description Michael Kay 2012-05-10 13:33:07 UTC 
The specification of outermost() says: The effect of the function call fn:outermost($nodes) is defined to be equivalent to the result of the expression $nodes[not(ancestor::node() intersect $nodes)].

However, it also says that the result is in document order with duplicates eliminated. The expression given does not achieve this. An equivalent expression that has this property would be

$nodes[not(ancestor::node() intersect $nodes)]/.
Comment 1 Michael Kay 2012-05-15 16:10:00 UTC 
The WG agreed to change the equivalent expression as described.
