Corona and Facebook - A few questions

I was reading through the documentation (http://docs.coronalabs.com/guide/social/implementFacebook/index.html) for Facebook, implementing it and showing a dialogue that posts to a user’s wall.  Here’s where I’m confused.

http://docs.coronalabs.com/api/library/facebook/showDialog.html

If I go into the Corona documentation for .showDialog above, it tells me the list of options I can choose to include for the “options” parameter.  However, almost immediately in the example there’s a “message” parameter unspecified in that list that’s used.  My question here is, is this somehow a “hidden” useable parameter, or was this phased out?  If it is still useable, then what are the other options I can use (such as if I can pass an image, link, etc)?

I know a lot of links point to here: https://developers.facebook.com/docs/javascript/reference/FB.ui  but that doesn’t typically help as far as using Corona SDK (and for the above paragraph, no mention of the message parameter)… for instance, in terms of naming conventions, IF there WASN’T an example of how you can pass “apprequests” into showDialog, that Facebook website does nothing to tell me that the keyword for this case is “apprequests,” if anything in that case I would have tried (and probably failed) by using “requests.”  

I feel like there has to be a full list of what one can do available, along with the correct syntax for each, but I haven’t found any.  Perhaps someone else has, or maybe figured it out?

Edit- Is it possible, perhaps, that the ‘options’ parameter for .showDialog() can contain the same elements as the .request()'s ‘attachment’ parameter?  That seems to be the only other place I’m seeing the message parameter used (and the others I need as well).

Actually the FB link is for Javascript based dialogs for web browsers.  For Corona SDK you need to be looking at either the iOS SDK or the Android SDK to get a feel for what’s supported.   See:  https://developers.facebook.com/docs/ios/ui-controls

Corona does a pass through to the native SDK, and the link above will give you a bunch of native jibberish, but you should be able to figure out what’s what.
