Hi Andrew ,
This is expected.  You can only have one of any given export otherwise there
would need to be logic for how to join arbitrary exports together.

If you want to define multiple nodelets in a single package just put them
into the same xml file. You can have multiple libraries in the xml file and
multiple classes in each library.
