XML used as a Template
Example comes from WebWisdomDB for storing training and education curricula objects -- PowerPoint, HTML, Photos ..
XML embedded as part of HTML “Web Page”
URL of Web Page invokes Servlet
e.g. http://witch.npac.syr.edu/servlet/TDLServlet/witch/index.tdl?USID=67
Servlet leaves HTML untouched but calls Java Methods to process XML tags
This Servlet processes <WW_… tags -- others are left for other servers or browser
