Align KDL Query grammar with prose 

The values() and props() accessors were only mentioned in the
grammaer, with no explanation whatsoever about what they were
supposed to do.

The val() accessor required an argument in the grammar while
the prose repeatedly mentions val() as equivalent to val(0).
