Comentarios

Los esquemas se cargan mediante el Add método , en cuyo momento el esquema está asociado a un identificador uniforme de recursos (URI) del espacio de nombres. En el caso de los esquemas XML, normalmente será la targetNamespace propiedad del esquema.

Aunque esta clase almacena esquemas XML y esquemas XDR, cualquier método y propiedad que toma o devuelve un XmlSchema objeto se aplica solo a esquemas XML.

Esta versión del producto admite la recomendación de esquema XML de World Wide Web Consortium (W3C) ubicada en esquema XML Parte 1: Estructuras y esquema XML Parte 2: Tipos de datos. Un esquema XML debe hacer referencia al espacio de nombres http://www.w3.org/2001/XMLSchema del esquema W3C en su elemento de esquema. Consulte el Add método para obtener un ejemplo.

XmlSchemaCollection puede ser utilizado por XmlValidatingReader para una validación de datos eficaz.
