Kenn,

You can define an EDataType whose instance class in the enum's class and that data type will allow nulls.

Alexandre,

This is a side-effect of the fact that Ecore (from EMF) is used to represent 
the metadata for (defined) profiles - in Ecore, an enumeration, like 
primitive (data) types, must have an implicit default. Unfortunately, I 
don't think there's much that can be done to change this. :(

Hi.
I created a profile where one of the stereotype properties points to an 
enumeraton. The property is set as [0..1] with default value null literal.
But it's just impossible to set a null value to this property. When the 
profile is defined (define menu) it chooses one of the literals as an 
arbitrary default value.
How can I create a property that accept nulls with Enumerations ?

Thanks
