This design-time message occurs if one or more of the saras of the saras property tries to specify that a rule above or rule below should be set to overprint, a feature not available with QuarkXPress.
The use of this feature will lead to a corresponding run-time message, and a result that is not as expected.
Solution
Use the Fix the Sara option of the popup menu to change the attribute that is generating this message (the detailed list of formats, and their respective support by QuarkXPress and InDesign, can be found here).
