Comentários

Esquemas são carregados usando o Add método, momento em que o esquema está associado a um URI (Uniform Resource Identifier) do namespace. Para esquemas XML, normalmente essa será a targetNamespace propriedade do esquema.

Embora essa classe armazene esquemas XML Schemas e XDR, qualquer método e propriedade que usa ou retorna uma XmlSchema se aplica somente a esquemas XML.

Esta versão do produto dá suporte à recomendação de esquema XML do W3C (World Wide Web Consortium) localizada na Parte 1 do Esquema XML: Estruturas e Esquema XML Parte 2: Tipos de dados. Um esquema XML deve referenciar o namespace http://www.w3.org/2001/XMLSchema do Esquema W3C em seu elemento de esquema. Consulte o Add método para obter um exemplo.

XmlSchemaCollection pode ser usado por XmlValidatingReader uma validação de dados eficiente.
