 Currently the following corrections from `correctionlib.schemav2` are supported:
 
 - `Formula`
-- `Binning` with uniform and non-uniform bin edges, simple scalar bin values, and `flow="clamp"`
+- `Binning` with uniform or non-uniform bin edges and `flow="clamp"`; bin contents can be either:
+  - all scalar values
+  - all `Formula`s
 - scalar constants
