Hi

The following works for me in QVTo:

mapping UML::DataType::convertDataType(in2out : Dict(UML::Element,
Ecore::EModelElement), context : Dict(String, OclAny)) : Ecore::EDataType
inherits Type::convertType {
instanceClassName :=
self.getValue(self.getAppliedStereotype('Ecore::EDataType'),
'instanceClassName').oclAsType(String);
eAnnotations := self.convertComments(in2out, context);
}

This manually traverses the stereotype using UML helper functions.
Unfortunately this requires an oclAsType to restore the 'known' type and
this is a problem in the traditional Ecore OCL implementation when that
type is a Collection.

My current thinking is that the OCL meta-model loader should treat
profiles in the same way as Complete OCL so that OCL expressions are
evaluated on the merged meta-model thereby allowing a type safe

instanceClassName := self.instanceClassName;

For now, I think getAppliedStereotype or custom Java may be your only
option.
