/**
 * Example JSP Custom Tag demonstrating three important concepts:
 * 
 * 1. use of the SqueakySand annotations for auto-generating the Tag Library Descriptor (.tld) file
 * 
 * 2. extending the CqSimpleTagSupport class from the CQ Blueprints library that provides many
 *    useful methods to make writing JSP Custom Tags for the CQ platform easier for developers
 * 
 * 3. accessing an OSGI service from within a JSP Custom Tag using one of the methods inherited
 *    from the CqSimpleTagSupport class
