>Should the definition of fn:boolean be changed to read "If $arg is a sequence
of one or more nodes, fn:boolean returns true"?

No, absolutely not. This would mean that a dynamic implementatation would have
to read the whole sequence, perhaps containing a million nodes, before it can
establish that there are no atomic values in the sequence and it can therefore
return true.
