Section 6.2.7 of F&O says (about numeric-unary-plus):
Semantically, this operation performs no operation.

However this behavior is inconsistent with numeric-unary-minus (and all other
numeric operators).

Specifically, consider the following query:
(+xs:int) instance of xs:int

According to the specification, this evaluates to true, however would this be
better casting the xs:int to an xs:integer? (i.e. should + behave the same as
--?)
