+<p>While you were viewing or updating [artifact_name], another user
+submitted an update to it.  That user's update has already
+taken effect.  Your update cannot be saved because your changes could
+overwrite the other user's changes.</p>
+
+<p>Note: if you have been viewing and updating [artifact_name] in multiple
+browser windows or tabs, it is possible that the "other user" is
+actually yourself.</p>
