In "my" ocaml version, 4.05, the line A of {lit : literal; mutable scope

type ab_literal =

is correct.

but in the ocaml version 4.02, the line A of {lit : literal; mutable
scope : int} is a syntax error.

Where can I find this error in the documentation and/or the 
announcement of this syntax change ?
