Hi,
Not a parameter (the parameter only applies to language or dbms) but you can add extension right after the model creation.
You use the ImportExtendedModelDefinition method on the model:
<<
ImportExtendedModelDefinition(ByVal Filename As String, ByVal Copy As Boolean = False) As BaseObject
Imports and uses an external ExtendeModelDefinition.
>>
the boolean parameter specify whether extension is embedded in the model.
Regards,
Marc
