Comentarios

La detección de servicios web XML implica detectar los servicios web XML disponibles, dada una dirección URL. La dirección URL suele apuntar a un documento de detección, que normalmente tiene una extensión de nombre de archivo .disco. El documento de detección, que es un documento XML, contiene referencias a información sobre la existencia de servicios web XML, como una descripción del servicio, un esquema de lenguaje de definición de esquema XML (XSD) u otro documento de detección. Esta clase representa el contenido del documento de detección; donde la References propiedad contiene una lista de las referencias contenidas en el documento de detección.
