As another example, consider the template:
{Location}-{Country}-{State}-{City}-{Caption} for a photo that has “Location” and “Caption”, but no “Country,” “City,” or “State.”. Assuming that location and caption are “Home” and “Having Fun” respectively, it becomes:
Home-Having Fun which is better than it would be without these special rules:
Home----Having Fun
