How about just define
type seq_t = super_node_t list
and nonlink_node_t =
[ `Text of string
| `Bold of seq_t ]
and link_node_t =
[ `Mref of string * nonlink_node_t list
| `See of string ]
and super_node_t =
[`Test of string |`Bold of seq_t | `Mref of string *
nonlink_node_t list | `See of string]
or similar ... not sure whether this satisfies your requirements though.
