Remarques

Bien que les opérations de requête-réponse ou de sollicitation-réponse soient logiquement corrélées dans le document WSDL (Web Services Description Language), les informations de corrélation concrètes seront spécifiées par une liaison. Par exemple, les messages de demande et de réponse peuvent être échangés dans le cadre d’une ou deux transmissions HTTP réelles.
