The model check produced 26 warning(s). The warnings are printed in red. The number of warnings found in each section is shown to the right of the section title in the table of contents and a reader can search for a warning by doing a find on the word "WARNINGS". Warnings are characteristics of the model that should be reviewed to ensure that the model satisfies the intent of the modeler.
