 * 
 * 	The jsp-property-groupType is used to group a number of
 * 	files so they can be given global property information.
 * 	All files so described are deemed to be JSP files.  The
 * 	following additional properties can be described:
 * 
 * 	    - Control whether EL is ignored.
 * 	    - Control whether scripting elements are invalid.
 * 	    - Indicate pageEncoding information.
 * 	    - Indicate that a resource is a JSP document (XML).
 * 	    - Prelude and Coda automatic includes.
 *             - Control whether the character sequence #{ is allowed
 *               when used as a String literal.
 *             - Control whether template text containing only
 *               whitespaces must be removed from the response output.
 * 	    - Indicate the default contentType information.
 * 	    - Indicate the default buffering model for JspWriter
 * 	    - Control whether error should be raised for the use of
 * 	      undeclared namespaces in a JSP page.
