A tool descriptor was modeled with a certain tool type which requires an "ISA_Plug-In" attribute but it is missing. This is
               a modeling error.
               	 
            
 
            	 
             
               		 
               		  
               - Model Administrator Response:
                  		  
               
-  Add an "ISA_Plug-In" attribute to the tool descriptor ("New Child" -> "ISA Plug-In") and define the missing attributes. Example:
                  If an input dialog was modeled (tool type "SWTDIALOG") you must specify a plug-in ID in the ISA Plug-In attribute.
