We have long had test cases that test for implementations that stray beyond XQuery 1.0 syntax (scenario parse-error). Some of these test cases are now valid instances of XQuery 1.1: 

WhereExpr020
K2-WhereExpr-1
K2-ExternalVariablesWithout-18

Consider WhereExpr020:

for $file in ($input-context//Folder)[1]/File
where true()
where false()
return $file/FileName


I suggest that these test cases be changed to the standard scenario and allow both an expected result and error XPST0003.
