The problem is not that '2' cannot be interpreted as xs:positiveInteger
but that numeric literals that do not contain a '.', 'e', or 'E' are 
given
the type xs:integer.
So the constants '2' and '3' are of type xs:integer and that's a
supertype of xs:positiveInteger and as such cannot be substituted.
