I'd have expected these to work the other way around - like if the Version is < 1995, then it's Ada 83. 

Might be weird to say it's Ada95 when the version is 1990/before 1995? But I'm not sure if there's a clear general sense, or language-specific sense, of what the intermediate values should mean.
