I'm trying to figure out how to describe/define the request body attributes/parameters for POST/PUT. Here is an example of what I'm trying to do, but I can't find it anywhere in the documentation (I wish there was a way to view the markdown of any public Apiary doc): http://docs.bynder.apiary.io/#reference/metaproperties/metaproperty-access/save-new-metaproperty
See the description and attribute definitions under the "Request" section? How do I do that?
