       @short  identifies the given module.

       @descr  This identifier can then be used at the service <type>ModuleManager</type>
               to get more information about this module.

               For identification the interface <type scope="com::sun::star::lang">XServiceInfo</type>
               is requested on the given module. Because all module service registrations must be unique
               this value can be queried and checked against the configuration.

               Since OOo 2.3.0 also the optional interface <type>XModule</type> will be used.
               If its exists it will be preferred.

       @param  Module
               Possible objects for this parameter can be the following one:
               <ul>
                   <li>
                       <b><type scope="com::sun::star::frame">XFrame</type></b><br>
                       A frame contains (against a component window) a controller.
                       Such controller represent the module (in case no model exists).
                   </li>
                   <li>
                       <b><type scope="com::sun::star::frame">XController</type></b><br>
                       A controller can be bound to a model. Then the model represent the module.
                       If no model exists - the controller is used for identification.
                   </li>
                   <li>
                       <b><type scope="com::sun::star::frame">XModel</type></b><br>
                       A model represent a module everytime and can be used for
                       identification directly.
                   </li>
               </ul>

       @throws <type scope="com::sun::star::lang">IllegalArgumentException</type>
               if the parameter Module is:
               <ul>
                   <li>an empty one</li>
                   <li>or does not provide one of the needed interface
                       XFrame, XController, XModel</li>
                   <li>or does not provide the needed interface XServiceInfo.</li>
               </ul>

       @throws <type>UnknownModuleException</type>
               if the given module could not be identified.
               Note: If the module represent a XFrame instance with does not contain
               a document, this exception is thrown too!

       @return An identifier for the given module.

               by thrown exceptions!
