However, if you have, say, Template:Happy infobox -- which is already using PI markup -- and you also have Template:Happy infobox/Draft, then the includeonly tags that are in Template:Happy infobox trigger the "Migrate this infobox" module. In our case that seems about right, you need to have had a Draft subpage. For example our emplate:Infobox_location/Draft is deleted but still we see the notice.
