DISCLAIMER: this is not a full answer but the app didn't show a comment only option)

I've been trying to set up a similar structure. For all I've researched and tried (very little documentation on this) you can only have one level of "childness".

I was trying: RWD > MyMain > AChild
Couldn't get it to work. Xml directives got all messed up.

Please, anyone who knows the above is wrong, pitch in.
