How about just including them with section headers?
For example, take
the following line of wiki syntax:
That seems to make sense. I'll give it a try and post an update.
Yes, that's true. The specifics of my proposed
implementation are
half-baked. The broader concept, though, is the idea of being able to
object-type articles as a way of imposing some kind of structure.
Maybe this is just fundamentally antithetical to the free-form nature
of Wikipedia, but I see that someone else is thinking along rather
similar lines with the proposal for a "Slotipedia."
It's a reasonable feature to support, the question is whether it can be
done in an easy to use and consistent fashion.
