OK, I'll found the answer:

I looked at worlddata1.1 db and in fact that field is used (-> comments). Here's an example out of tradeskillrecipe.txt:

#ID,tradeskill,skillneeded,trivial,product,product 2,failproduct,productcount,i1,i2,i3,i4,i5,i6,i7,i8 ,i9,i10,comments
INSERT INTO tradeskillrecipe VALUES (3003,64,82,82,8502,0,0,5,8066,8060,8055,8050,0,0, 0,0,0,0,'CLASS 3 Wood Point Arrow');
