Also, the vertical stripe on the right side of the editor panel is designed to display the errors found during the validation process and to help you locate them in the document. The stripe contains the following:

                  displayed, open the
                        Preferences dialog box , go
                  to , and specify the desired limit in the Maximum number of validation highlights
