Overlay Name

Type an appropriate name for the overlay. This also becomes the tag name.

Allowable Values

Type in the allowable values for the overlay/tag, not separated by any punctuation or spaces (for example, CRUD); the matrix cell is case sensitive, so type the values exactly as they are to be entered.

Mutually Exclusive

If you want only one allowable value to be set in a matrix cell at a time, select this checkbox. (This makes the Tagged Value an Enum type.)

If you want to allow any combination of values to be set in a matrix cell at a time, clear the checkbox. (This makes the Tagged Value a Custom type.)

OK

Click on this button to save the new overlay/Tagged Value.

You can now view the overlay on the 'Tagged Value Types' tab of the 'UML Types' dialog, in the format:

     Type=Enum;Values=C,R,U,D;MatrixOverlay=true;
