I am going to do a thread later on making a set of large oak gates using the Domino XL and shop made oak tenons but I will put a few pics up to show how I make them. It works for me.
I plane up lengths of oak 1m long to the dimensions of the domino width required, in this case 70mm and with the domino cutter 14mm I thickness the domino tenon to 13.5m.
Then on the router table use an ovolo bit to round over the edges. This puts a slight groove on either shoulder.
Then using a V groove cutter in the router table I put a number of V grooves the full length (how many depends on the width of the tenon) to allow glue/air to flow.
Hope these pics help
