/**
* Used to parse shortcut elements for simple built-in components such as
* {@link org.mule.component.simple.EchoComponent} and
* {@link org.mule.component.simple.LogComponent}. This allows shortcuts like
* for example <i><mule:bridge-service/></i> to be used instead of having to
* use the <i><mule:service/></i> element and specify the class name (and
* scope) for built-in components that don't require configuration. <p/> <b>This
* DefinitionParser should only be used for state-less components.</b> <p/> In order
* to further customize components and use serviceFactory properties the
* <mule:service/> element should be used.
