O seguinte XML é gerado para este exemplo de código.

<?xml version="1.0" encoding="IBM437"?>
<schema elementFormDefault="qualified" targetNamespace="http://www.w3.org/2001/05/XMLInfoset" xmlns="http://www.w3.org/2001/XMLSchema">
  <import namespace="http://www.example.com/IPO" />
  <include schemaLocation="example.xsd" />
</schema>

Observações

O documento de esquema incluído deve cumprir uma das seguintes condições:

O esquema incluído deve ter o mesmo namespace de destino do documento de esquema que o contém.

OR

O esquema incluído não pode ter um especificado targetNamespace; o targetNamespace atributo deve ser nulo.

XmlSchemaInclude adiciona todos os componentes do esquema dos esquemas incluídos que têm o mesmo espaço de nomes alvo (ou nenhum espaço de nomes alvo especificado) ao esquema contém.
