Changes to this class. What the people have been up to:
$Log: AbstractWMSRequestValidator.java,v $
Revision 1.4 2006/11/07 09:56:11 poth
support for GetMap SLD parameter added
Revision 1.3 2006/08/10 07:17:52 poth
bug fix - removing Arrays.asList calls for transforming op.geValues because accoring to refactoring this method it already returns a list
Revision 1.2 2006/08/02 09:45:09 poth
changes required as consequence of changing OperationParameter
Revision 1.1 2006/07/23 08:44:53 poth
refactoring - moved validators assigned to OWS into specialized packages
Revision 1.9 2006/07/12 14:46:16 poth
