Just like:

/// Forwards members to [Whatever]
auto opDispatch......

and then the documentation shows that with the link so they can 
refer to the other thing easily enough. That's what I did on my 
thing for example

http://dpldocs.info/experimental-docs/arsd.dom.ElementCollection.opDispatch.html

(possible I could make my doc gen recognize the pattern and paste 
in generated docs too, but I personally like the link enough)
