My Dwyer mast on my 192 has a tang riveted to the side of the mast, and a fork type swage on the shroud, which attaches to the tang with a clevis pin and ring-ding. Look for Loos Fork Ends (Swage) on this page:

I can't imagine any reason for it to be different on a Z-Spars mast (which is the other mfg that did masts for 222/192.) There is no reason to permanently affix standing rigging to the mast, as in, rivet the standing rigging to the mast. Standing rigging should always be removable/replaceable.
