11.3. Add Validation to Your Application

Procedure 11.1. Add Validation to Your Application

Specify message validation in the descriptor of your SwitchYard application by editing the switchyard.xml file using the JBoss Developer Studio SwitchYard Editor.
The qualified name of the type being validated is defined along with the validator implementation. This allows validation to be a declarative aspect of a SwitchYard application, as the runtime will automatically register and execute validators in the course of a message exchange.
```
 
<validates>
   <validate.xml schemaType="XML_SCHEMA"
                   name="{urn:example}MyBook">
      <schemaFiles><entry file="/xsd/orders.xsd"/></schemaFiles>
   </validate.xml>
</validates>    
    
```
