Remarques

La découverte de services web XML implique la découverte des services Web XML disponibles, en fonction d’une URL. L’URL pointe généralement vers un document de découverte, qui a généralement une extension de nom de fichier .disco. Le document de découverte, qui est un document XML, contient des références à des informations sur l’existence des services Web XML, tels qu’une description de service, un schéma de langage XSD (XML Schema Definition) ou un autre document de découverte. Cette classe représente le contenu du document de découverte ; où la References propriété contient une liste des références contenues dans le document de découverte.
