type Comment = Maybe String

Comments can be attached to most things, but not all of them will exist.

data Module

The whole Haskell module.

data Decl

There are essentially simple types, and complex types, each of which can be either restricted or extended. There are four kinds of complex type: choices, sequences, named groups, or a simple element with content.
