In a derived class, the ServiceDescriptionFormatExtension class allows users to define extensibility elements in addition to those defined in the Web Services Description Language (WSDL) specification. Extensibility elements can be added to a ServiceDescription at any of several levels within the class hierarchy. Thus many classes derived from the DocumentableItem class (including the ServiceDescription class) have an Extensions property, which returns a ServiceDescriptionFormatExtensionCollection.
