Hinweise

Bei der XML-Webdienstermittlung werden die verfügbaren XML-Webdienste ermittelt, die als URL angegeben sind. Eine Die URL verweist in der Regel auf ein Ermittlungsdokument, das in der Regel die Dateinamenerweiterung .disco aufweist. Das Ermittlungsdokument enthält Verweise auf Informationen über das Vorhandensein von XML-Webdiensten. Diese Verweise können auf Dienstbeschreibungen, XSD-Schemas oder andere Ermittlungsdokumente verweisen. Diese Klasse stellt einen Verweis auf ein XSD-Schema dar.

In einem Ermittlungsdokument ist ein Verweis auf ein XSD-Schema in einem schemaRef XML-Element enthalten. Das schemaRef XML-Element verfügt über einen XML-Namespace und ein ref Attribut. Der Wert des XML-Namespace muss mit der Konstanten Namespace übereinstimmen. Der Wert des Attributs ref wird in der Ref -Eigenschaft platziert.
