Three remarks

Nice, Boris. I have only minor comments:

  1. I think the "noncommutative counterpart" needs some more explanation.
  2. What do you think of discussing the relation to antisymmetry of order?
  3. What about more structure by (sub)headings?

1. "noncommutative counterpart" — on one hand, I am waiting for a book from our library about this point; but on the other hand, it is anyway beyond the form "If X is similar to a part of Y and also Y is similar to a part of X then X and Y are similar (to each other)" and only inspired by it.
2. "relation to antisymmetry of order" — you are right, this should be noted.
3. "structure by (sub)headings" — I also feel the need, but the article is so short, I do not see which headings; do you? Boris Tsirelson 06:23, 26 September 2010 (UTC)
As for headings: "Examples" is obvious, I think.
The introduction could say something like: "(Remark) In contrast to most mathematical terms this only gives the general form, the pattern, of a statement instead of a definite and precise definition."
Then the explanation following it could have the heading "The general pattern" (or similar). For tactical reasons :-) I do not make changes myself.
