Represents the maxExclusive element from XML Schema as specified by the World Wide Web Consortium (W3C). This class can be used to specify a restriction on the maximum value of a simpleType element. The element value must be less than the value of the maxExclusive element.

Namespace: System.Xml.Schema
Assembly: System.Xml (in system.xml.dll)

'Declaration
