In dissect_attributes(), you could create a subtree for the attribute you
dissect, using proto_item_add_subtree() and a new ett_... variable. 

E.g. for SNPA, you'd define a string hf
        { &hf_idrp_snpa,
          { "SNPA", "idrp.snpa",
            FT_STRING, BASE_NONE, NULL, 0, NULL, HFILL }
        },

and call proto_tree_add_item(attr_tree, hf_idrp_snpa, tvb, offset, snpa_len,
ENC_ASCII|ENC_NA);
in the for(...nb_of_snpa...) loop

regards
Martin
