	* <PRE>
    * A module's deployment descriptor file always contains
	* a document type identifier, DOCTYPE.  The DOCTYPE statement 
	* contains the module DTD version number in the label of the 
	* statement.
	*
	* 	The format of the DOCTYPE statement is:
	*<ul>
	*	<!DOCTYPE root_element PUBLIC 
	*	"-//organization//label//language" "location">
	*</ul>
	*
	* root_element - is the name of the root document in the DTD.
	* organization  - is the name of the organization responsible 
	*                 for the creation and maintenance of the DTD 
	*                 being referenced.
	* label - is a unique descriptive name for the public text being 
	*                 referenced.  
	* language - is the ISO 639 language id representing the natural 
	*                 language encoding of th DTD.
	* location - is the URL of the DTD.
	*
	* An example Java EE deployment descriptor DOCTYPE statement is:
	*<ul>
	*   <!DOCTYPE application-client PUBLIC
    *   "-//Sun Microsystems, Inc.//DTD J2EE Application Client 1.3//EN"
    *   "http://java.sun.com/dtd/application-client_1_3.dtd">
	*</ul>
	* In this example the label is, "DTD J2EE Application Client 1.3", 
	* and the DTD version number is 1.3. A call to getModuleDTDVersion 
	* would return a string containing, "1.3".
	* </PRE>
    *
    * This method is being deprecated.  With the addition of multiple
    * deployment descritors in components for J2EE 1.4 this method is
