Criteria for languages?

[Caoimhin O Donnaile]

The Ethnologue has a discussion of language vs. dialect
criteria in its introduction:

As regards Scottish Standard English (en-scottish, if I remember),
that is just English as spoken by, for example, clearly-spoken
Scottish Members of Parliament in Westminster.  I can't see that
ever being considered a separate language.  Scots on the other
hand (sco) is already considered a separate language.  For written
examples see http://sco.wikipedia.org/
