/**
 * Custom class for supporting primitive XSD data type positiveInteger
 * <p/>
 * positiveInteger is derived from nonNegativeInteger by setting the value of minInclusive to be 1.
 * This results in the standard mathematical concept of the positive integer numbers. The value
 * space of positiveInteger is the infinite set {1,2,...}.
