This goes too far. Andreas's comments are often quite valuable and bear study, 
and it's typically not that hard to figure them out. Also, Andreas has 
repeatedly shown willingness to expand on his comments when asked nicely, or 
when people clearly misunderstand them. In practice his style is a reasonable 
way to help us out, even if it's terser than the style most people use.

In this case, I expect that Andreas's point is that ISO 639-2 has the following 
entries:

ayc - Southern (Altiplano) Aymara, sometimes called "Aymara" in English
ayr - Central Aymara -- Jaqaru and (now nearly extinct) Kawki
aym - inclusive code for both ayc and ayr

In contrast, ISO 639-1 has just "ay", corresponding to ISO 639-2's "aym". So 
could you explain why is it technically correct to replace "ayc" with "ay"?

Some background: "ayc" has about 2 million speakers; "ayr" has about 700. "aym" 
doesn't have an universally agreed-upon name in English; some call it "Aymaran", 
some "Aymara", some "Jaqi", and some "Aru". There is opportunity for confusion 
here, due to the multiple meanings of the English word "Aymara".
