/**

 * @dtf.author Rodney Gomes
 * 
 * @dtf.tag.desc The case tag is used in the switch tag and identifies a possible
 *               case to match the property value from the switch tag. If there
 *               is a match then the case children tags will be executed. 
 *               
 * @dtf.tag.example 
 * <switch property="${test}">
 *     <case value="1">
 *          <log>Switch case #1</log>
 *     </case> 
 *     <case value="2">
 *         <log>Switch case #2</log>
 *     </case>
 *     <default>
 *         <log>Default case called</log>
 *     </default>
