Ignore body section when it was combined with attributes section in any parent sections [Payload\Resource\Action]

When I try to write attributes section to describe payload fields of request body [POST]. while it couldn' t render the body section when the attributes sections has been added into request section. Could aglio fix this issue.
I compared it with the apiary.io which could be compatible with those two sections written into any parent sections [payload\resource\action].

The report names Payload\Resource\Action and a POST request combining body and attributes sections, but no repository files or tests. Start by reproducing that rendering case, then trace the relevant API Blueprint parsing and rendering path. Done means the body renders when attributes are present in any named parent section, matching apiary.io.
