If I can get past the DC math filter without reprimand, sorry not today... I think his point that the {} empty set is a member of any set was the Ah-ha moment for me. That's what allows the as="xs:string?" to succeed rather than report the error. The empty set isn't a _member_ of every set. {} isn't a member of {1,2,3} for example. It is a member of {{}} though (the set with one member, the empty set) It is a _subset_ of every set.
