Validate out-of-scope links
The Validate Links command detects any out-of-scope links, that is, links that point to documents that are not in the current map. This command also applies to reltables: If a reltable contains a reference to a topic that is not in the map scope, the Validate Links command returns an out-of-scope error.
You cannot publish a map that contains out-of-scope links. You should run this command regularly to confirm that all your links are correct.
