Comentários

XmlSchemaSimpleContent é usado para indicar que o modelo de conteúdo do novo tipo contém apenas dados de caractere e nenhum elemento. Ele faz isso através XmlSchemaSimpleContentExtension ou XmlSchemaSimpleContentRestriction.

Construtores

XmlSchemaSimpleContent()

Inicializa uma nova instância da classe XmlSchemaSimpleContent.
