Apiary: Is there a way to define options for parameters?

I would like to define options for Apiary parameters, I'm currently listing them in the description:

• measurement = m (optional, string, m) ... measurement e.g. m = meters, km = kilometers, yd = yards, mi = miles

You can enumerate the possible values of an URI query parameter and discuss it in the parameter discussion like so:

+ Parameters
    + measurement = `m` (optional, string) ... measurement units

        Any discussion here...

        e.g. explanation of **values** listed bellow are.

        + Values
            + `m`
            + `mi`
            + `yd`
