Hi Pinaki,
They can't be distinguished in the current version of SDO metadata, you
need to look at the original XSD. The next version of SDO (SDO 3) is
planning to provide an api for accessing extended XSD metadata. In
Tuscany, you can currently determine this by downcasting to the EMF
implementation class, although we don't recommend people do that:
System.out.println(" Property isID: " +
((property.getType().isDataType()) && ((EAttribute)property).isID()));
