Observações

A descoberta de serviços Web XML envolve a descoberta dos serviços Web XML disponíveis fornecidos, uma URL. R O URL normalmente aponta para um documento de descoberta, que normalmente tem uma extensão de nome de ficheiro .disco. O documento de descoberta contém referências a informações sobre a existência de serviços Web XML. Estas referências podem referir-se a descrições de serviços, esquemas XSD ou outros documentos de descoberta. Esta classe representa uma referência a um esquema XSD.

Dentro de um documento de descoberta, uma referência a um esquema XSD está contida num schemaRef elemento XML. O schemaRef elemento XML tem um namespace XML e um ref atributo. O valor do namespace XML deve corresponder à Namespace constante. O valor do ref atributo é colocado na Ref propriedade.
