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