The DITA OT does not have any support for this that I know of. This means you have the added complexity, or flexibility (if you are an optimist) of deciding what markup will be used to put something in the margin. What this will come down to is a customization of the DITA OT's XSLT to generate XSLFO in a form that RenderX XEP will do what you want.
I have no idea how much work this would be, but one of our partners or our Professional Services team could look into it.
If you are lucky someone out there may have created a plug-in for the DITA OT that might help, though I suspect any such solution would probably be written specifically to solve a given organizations own needs.
