consider below model:

class Person
{
	String firstName
	String lastName
	
	derived String fullName 
	get	{ 
		firstName + " " + lastName
	}
	set 	{
		var array = fullName.split(" ")
		firstName = array.get(0)
		lastName = array.get(1)
	}
}

Xcore generator seems to do not generate setter for feature in any case.

is it just reserved keyword?

I can define an operation for my purpose, but I don't want to increase pointless feature for readability.

And I want to define setter for non-derived feature too.
Because I want to fire notifications when derive feature value is invalid.

Thanks.

Yes, by default we make derived imply transient, volatile, and readonly
but haven't added keywords to specify the inverse of those things.

That's not supported yet either.

If you open a bugzilla, I'll explore what can be done for the next
release. Even derived multi-valued features are not working so nicely...
