Description Michael Kay 2014-03-11 00:13:00 UTC 
When a map expression has a key that evaluates to an empty sequence, we say:

Each KeyExpr expression is evaluated and atomized; a dynamic error occurs if the result is not a single atomic value.

It should be a type error not a dynamic error.
Comment 1 Michael Kay 2014-03-27 23:17:33 UTC 
The WG agreed this should be a type error. Fixed.
