* Controller for the parsing of a JSP page.

* A translation unit (JSP source file and any files included via the

* written with different syntaxes (currently the original JSP syntax,
* as well as the XML syntax (as of JSP 1.2)). This class encapsulates
* the behavior related to the selection and invocation of
* the proper parser.
