Restriction on strings used with D-Bus

There are a lot of restrictions for strings used in D-Bus. OBus only verifies strings when a message is sent or received

type error = {

typ : string;
(*
Type of string ("string", "bus name", "error name", "path", ...)
*)
str : string;
(*
The string which fail to validate
*)
ofs : int;
(*
is the position in bytes where the validation failed
*)
msg : string;
(*
explains why the string failed to validate
*)

}

val typ : error -> string
