Yes, that is indeed the problem.  If there is a MOF 1.3 metamodel available 
for the diagram exchange metamodel, then you can extend PEAK to handle the 
diagram class.  Alternatively, you can define your own version of the UML 
1.4 metamodel that simply adds a Diagram class, so there won't be a problem 
when PEAK reads the top-level objects.  Depending on what objects you 
access, however, you may have to define other dummy classes of that sort.
