Both sets of comments I received were helpful, supportive, and constructive. Reviewer 1's comments went into more depth than Reviewer 2's comments.

One reviewer accepted the paper with minor revisions and the other did not explicitly say whether he rejected it or asked for a major revisions. The latter reviewer's reason was that I did not include (for him) relevant literature. But, I repeat, I'm not sure what was his decision.
