XmlSchemaMaxExclusiveFacet Classe

Definizione

Rappresenta l'elemento maxExclusive dallo schema XML come specificato da World Wide Web Consortium (W3C). Questa classe può essere utilizzata per specificare una limitazione al valore massimo di un elemento simpleType. Il valore dell'elemento deve essere inferiore al valore dell'elemento maxExclusive.
