XML Files with Embedded XSD Statements

This section provides a tutorial example on how to include XSD statements inside XML files. Embedded or inline XSD statements should appear inside a parent element and before target elements the schema is applied to.

Can we embed XSD statements inside an XML file similar to DTD statements? The answer seems to be yes. An embedded XML schema is also called an inline XML schema.

I found 2 formats to do this on the Internet:

1. Using "#id" for the schema location - This format is supported by XSV (XML Schema Validator):

<?xml version="1.0"?>
<class xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="#mySchema">
 <xs:schema id="mySchema" xmlns:xs="http://www.w3.org/2001/XMLSchema">
   <xs:element name="class" type="xs:any"/>
   <xs:element name="student" type="xs:string"/>
 </xs:schema>
 <student>Herong Yang</student>
 <student>John Smith</student>
</class>

2: Using no schema location attribute - This format is supported by .NET Framework:

<?xml version="1.0"?>
<class>
  <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="student" type="xs:string"/>
  </xs:schema>
  <student>Herong Yang</student>
  <student>John Smith</student>
</class>
