Suppose you annotate a host view and tag elements in linked models. If the linked model later becomes unavailable, the tags may or may not persist, as follows.
| When the linked model is... | Tags for linked elements... | When the linked model is restored, ... |
|---|---|---|
| Unloaded or missing | no longer display in the host view. | tags for linked elements display in the correct positions. |
| Removed or deleted | are deleted from the host project. | tags must be reapplied to linked elements. |
