Many frameworks such as Spring, MyBatis or Hibernate rely part of their functionality or configuration on xml definitions where the programmer declares classes of his domain to be used by the framework.
Using Rinzo standing on a tag body or attribute value part it is possible to get class names autocompletion propossals. Ie:
<class name="arra"> will be <class name="java.util.ArrayList">
<servlet-class>log</servlet-class> will be <servlet-class>ar.edu.utn.frba.tadp.servlets.Login</servlet-class>
