Schema

Hi,

   See this tutorial from w3schools about XML namespaces:

Yes, you will need 3 schema:

xs:schema xmlns:a=“urn:areatype“ elementFormDefault=“qualified“ xmlns:xs=“http://www.w3.org/2001/XMLSchema“>
<xs:import schemaLocation=“.\areatype.xsd“ namespace=“urn:areatype“ />
<xs:element name=“Area“ type=“a:areaType“ />
</xs:schema>

xs:schema xmlns:tns=“urn:areatype“ elementFormDefault=“qualified“ targetNamespace=“urn:areatype“ xmlns:xs=“http://www.w3.org/2001/XMLSchema“>
<xs:import schemaLocation=“.\place.xsd“ />
<xs:complexType name=“areaType“>
<xs:sequence>
<xs:element name=“street“>
<xs:complexType>
<xs:sequence>
<xs:element name=“house“ type=“xs:string“ />
<xs:element ref=“place“ />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:schema>

xs:schema xmlns:xs=“http://www.w3.org/2001/XMLSchema“>
<xs:element name=“place“ type=“place“ />
<xs:complexType name=“place“>
<xs:sequence>
<xs:element name=“Number“ type=“xs:string“ />
</xs:sequence>
</xs:complexType>
</xs:schema>

These schemas will validate this Xml:

Area xmlns:a=“urn:areatype“>
<a:street>
<a:house />
<place>
<Number>1</Number>
</place>
</a:street>
</Area>
