I was showing off Mathematica's capabilities to someone by making a quick and dirty geographic travelling salesman calculation complete with mapping, when I noticed that Mathematica thinks that both Svalbard and the Isle of Man are separate countries.  Why is this?  Is this a bug?

CountryData["Europe"] includes both "IsleOfMan" (part of UK) and "Svalbard" (part of Norway).  Is this a bug?  The documentation says that CountryData knows countries and "country like entities", so I thought that these are separate because they are geographically separate islands (though the Isle of Man is hardly far from the mainland...)  But Alaska or Hawaii are not listed by CountryData["NorthAmerica"].

So, is this a bug, or is it intentional?  It doesn't look like one of those debated or unclear cases which will upset somebody's political sensibilities one way or another, so why are these regions separate in Mathematica's database?
