yes, you do have to metamodel this capability. It is implemented using 
references in GME. A proxy is a reference. Check out the the 
meta-metamodel that comes with the GME install for an example.

Furthermore, your interpreter will have to handle this as well which is 
much harder than creating the metamodel.

Hope this helps,
