XmlSchemaSequence Classe

Définition

Représente l’élément sequence (compositeur) issu d’un schéma XML comme spécifié par le W3C (World Wide Web Consortium).Represents the sequence element (compositor) from the XML Schema as specified by the World Wide Web Consortium (W3C). sequence requiert l'affichage des éléments du groupe selon l'ordre spécifié dans l'élément conteneur.The sequence requires the elements in the group to appear in the specified sequence within the containing element.
