Topic: Modifier extension on ElementDefinition
Shamil Nizamov (Sep 19 2018 at 20:56):
The modifier extension can be used "on a few specially selected data types", ElementDefinition included. But ElementDefinition defines every element in a resource. This leads to a conclusion that modifier extension can be used on any element including those that "have a data type", does it not?

ElementDefinition defines the elements, but the elements don't extend from ElementDefinition.

So you can use modifierExtension in StructureDefinition.snapshot.element and StructureDefinition.differential.element. But that doesn't mean you can use modifierExtension in Address.use just because Address is defined using StructureDefinition.
