We show that in Seyfert 1s, coronal lines Fe X, Fe XI, Fe XIV...), whose emission region shares common characteristics with the WA, could be formed in the WA. Unlike the absorption edges, such as those of O VII and O VIII observed in soft X-rays which are produced by the WA, these lines strongly constrain the physical parameters of the WA, especially the hydrogen density.
