>While we are considering these static typing rules, would it not make sense to
stipulate that fn:floor and fn:ceiling should return an xs:integer for
xs:decimal arguments?

Sounds logical, but there's one hitch: implementations are permitted to support
a smaller range of values for xs:integer than they support for xs:decimal.
