Right now only request object is parsed for ApiMember attributes to generate documentation page. We've added support to parse all properties and show documentation for "subtypes".

Is it that much more work to add documentation to parse response object in similar manner? And show documentation for it as well?

Ideally it'd be in sections on the meta doc page.
Request
request types

Response
response types

I can take a stab at it, but might misdesign again.
