Hi,

If I understand your question correctly, you have in your metamodel a top 
level package, which contains one or more subpackages with classes within 
them, for example like this:

<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
   xmlns:xmi="http://www.omg.org/XMI"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
   xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"; 
name="TopLevelPackage"
   nsURI="http://www.examplemm.org/ExampleMM"; nsPrefix="examplemm">
 <eClassifiers xsi:type="ecore:EClass" name="ClazzA"/>
 <eSubpackages name="SubPackageB" 
nsURI="http://www.examplemm.org/ExampleMM/SubPackageB";>
   <eClassifiers xsi:type="ecore:EClass" name="ClazzB1"/>
   <eClassifiers xsi:type="ecore:EClass" name="ClazzB2"/>
 </eSubpackages>
 <eSubpackages name="SubPackageC" 
nsURI="http://www.examplemm.org/ExampleMM/SubPackageB";>
   <eClassifiers xsi:type="ecore:EClass" name="ClassC1"/>
 </eSubpackages>
</ecore:EPackage>

In this case, all classifiers from this metamodel should be available to 
MOFSCript as if they were defined at the top level.

Regards,
Jon
