It's just required when the Loop is inside a Form and the value of the  
Loop's formState parameter is different from LoopFormState.NONE. So you  
don't need to provide a ValueEncoder when you add formState="none" to your  
Loop.

It is because Loop is trying to submit values inside it.

It's used by Loop in order to restore the objects during form submission  
and apply the submitted values to them.

Answered above.
