This collection can either contain instances of classes deriving from ServiceDescriptionFormatExtension, or instances of the XmlElement class. In a derived class, ServiceDescriptionFormatExtension class allows users to define extensibility elements in addition to those defined in the Web Services Description Language (WSDL) specification. Use these in your ServiceDescriptionFormatExtensionCollection if you know in advance the type of extensibility element you want to make. Use an XmlElement when you do not know the format of an element in advance.
