The following categores are specified by C++:

    static const category none		= 0;
    static const category ctype 	= 1L << 0;
    static const category numeric 	= 1L << 1;
    static const category collate  	= 1L << 2;
    static const category time 		= 1L << 3;
    static const category monetary 	= 1L << 4;
    static const category messages 	= 1L << 5;
    static const category all 		= (collate | ctype | monetary |
				 	   numeric | time  | messages);

There are more for C/POSIX.
