== Relationship to the [[Borel hierarchy]]? ==
We seem to have almost the same content on the page for the [[Borel hierarchy]] and if one blurs one's eyes, they cannot be told apart. Perhaps some clarifying distinction should be drawn. Well, I mean, the Borel hierarchy starts with <math>\mathbf{\Sigma}^0_1</math> and the analytic hierarchy does not show up till much later, as <math>\mathbf{\Sigma}^1_1</math>, but it seems that perhaps this should be pointed out in the opening paragraphs.
