   </property>]*

</validator>

The <validator-id> element assigns a unique identifier for the validator, and the <validator-class> element contains the fully qualified class name that implements the javax.faces.validator.Validator interface:

<validator>

  <validator-id>com.mycompany.MyValidator</converter-id>

  <validator-class>

    com.mycompany.jsf.MyValidator

  </validator-class>

</validator>

The <attribute> and <property> elements provide information about the component's generic attributes and type-safe converter properties, respectively, that may be used by a development tool to help a developer use the validator, the same way for the <component> element.
