I thought someone would offer this... :)

But xs:boolean is a special case (shall I say restriction) of the
xs:integer type. Certainly, it is equivalent to a binary digit and
with a binary digit one can build everything.

I think in math one can start just with 0 and 1 and then build
everything else, and the name of Peano comes to mind.


In case we want to skip a few theoretical steps for convenience, we
will have the xs:integer type.
