11.2. Message Validation
Here is a sample that depicts message validation.
Message Content:
<MyBook xmlns="example"> <Chapter1/> <Chapter2/> </MyBook>
This is the associated XML Schema definition:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="example"
xmlns:orders="example">
<element name="MyBook" type="example:MyBook"/>
<complexType name="MyBook">
<sequence>
<element name="Chapter1" type="string"/>
</sequence>
</complexType>
</schema>
The XML content is still well-formed, but it has a
Chapter2 element that is not declared as the child of MyBook element in the XML schema. Hence the content cannot be validated against the schema.
