/**
 * Custom class for supporting primitive XSD data type negativeinteger
 * <p/>
 * negativeInteger is derived from nonPositiveInteger by setting the
 * value of maxInclusive to be -1. This results in the standard
 * mathematical concept of the negative integers. The value space of
 * negativeInteger is the infinite set {...,-2,-1}.
 * The base type of negativeInteger is nonPositiveInteger.
