So let us say a certain amateur XML editor has been a little gratuitous with the copy/paste feature.  

If I have a bunch of different continents defined on a board of different names, but with the same ContinentID, but different territoryIDs associated with each of them, what will be the consequences (if any)?

Never mind, it apparently auto-updates continentID when you import back in the xml file.  

It's probably an automated feature, but I'm still going to give tom props for it.
