why does () eq () not return true?


the logical thing for it to return would be an error, the new at 2.0 operators really act on single items, explicitly because not everyone wanted the implied existential quantification of the xpath 1 operators which act on sequences (aka node sets).

But then they added the general idiom that input of () returns ()
to make things seem cozy to sql people...
