Actually, I believe the problem is that the EDataTypes created by the
KM3 to Ecore transformation do not have an appropriate value for

We do not like to have our metamodels point to Ecore elements (e.g.,
EString, EInteger). The reason is that, in such a case, the metamodel
somehow becomes an extension of the metametamodel.
That being said, you can always modify the KM3 to Ecore transformation
to use EString, EInteger, etc. Or, you may also change this
transformation to initialize the instanceClassName attributes of the
generated EDataTypes. The transformation is available in the ATL
Future versions of KM3 will come with this mechanism built-in ;-).
