>>> As an alternative approach we could get round this by specifying the angles of universality. e.g., UNIVERSAL 60°N - 10°S. This is a more scientific way of doing it. Again, I look for your comments.<<<<
In cataloging sundials in museum collections and elsewhere, this is precisely the approach I take. Traditionally, the term "universal" is understood to imply only a limited range of latitudes (perhaps due to the term's eurocentric origins) and really is shorthand for "serving multiple latitudes." Given the long history of the term, I don't want to change it or introduce "semi-universal," etc. But as you suggest, I think it best to identify the parameters in which the dial is in fact "universal."
