After reading above link, seems to me that CDATA tag is used to drive
parsing what to do in such cases. When I looked at the test cases,
parsing routing is adding CDATA tag internally if some entity is defined
inside javascript. Why parser is adding tag?

I traced the code for SAX test cases, the output change is see is
because of new callback parser is giving in case of
XML_WAR_UNDECLARED_ENTITY. Could you help me understand what action
application can take on this callback.
