Note that this is only for destination guides. If you use it on other pages, you'll get breadcrumb menus all right, but you'll mess up other software. Please, don't do that.

It is not needed for breadcrumb navigation on district subpages, but it should be used anyway to ensure that the RDF relationships are correct.

To use it, add {{isPartOf|name of other place}} to the bottom of a destination guide. The name of the other place does not have be in URL-encoded format - spaces are OK.
