Comentarios

El documento de esquema incluido debe cumplir una de las condiciones siguientes:

El esquema incluido debe tener el mismo espacio de nombres de destino que el documento de esquema contenedor.

OR

El esquema incluido no puede tener un especificado targetNamespace; el targetNamespace atributo debe ser NULL.

XmlSchemaInclude agrega todos los componentes de esquema de los esquemas incluidos que tienen el mismo espacio de nombres de destino (o ningún espacio de nombres de destino especificado) al esquema contenedor.
