XML Schema

Please, send all comments, bug-reports, and contributions to Jiri.Jirat@systinet.com. Thank you very much.

1. XML Schema

Both target namespaces are the same (null), so inclusion won't have any further effects on the namespace settings in the included schema. Schema Representation Constraint: Inclusion Constraints and Semantics .

Valid document

<root xsi:noNamespaceSchemaLocation="correct_0.xsd" xmlns="" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<x>dhhglh</x>
</root>

Invalid document

<root xsi:noNamespaceSchemaLocation="correct_0.xsd" xmlns="" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<foo:x xmlns:foo="http://foo" >dhhglh</foo:x>
</root>

Correct XML Schema (correct_0.xsd)

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" >

<xsd:include schemaLocation="correct_1.xsd"/>

<xsd:element name="root" type="myType"/>
</xsd:schema>

Correct XML Schema (correct_1.xsd)

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" >

  <xsd:complexType name="myType">
    <xsd:sequence>
      <xsd:element name="x" minOccurs="1" maxOccurs="1" type="xsd:string"/>
    </xsd:sequence>
  </xsd:complexType>
</xsd:schema>
