Comentários

Essa coleção pode conter instâncias de classes derivadas ou ServiceDescriptionFormatExtensioninstâncias da XmlElement classe. Em uma classe derivada, ServiceDescriptionFormatExtension a classe permite que os usuários definam elementos de extensibilidade, além daqueles definidos na especificação WSDL (Linguagem de Descrição dos Serviços Web). Use-os em seu ServiceDescriptionFormatExtensionCollection se você souber com antecedência o tipo de elemento de extensibilidade que deseja criar. Use um XmlElement quando você não souber o formato de um elemento com antecedência.
