In application domain models, we use attributes to make the application work and other ones to store data. It would improve the UX of the domain model if we are able to add a little icon to an attribute that explains what the attribute is used for in the application.
E.g. When it's a application driven attribute (conditional visibility, workflow status, etc..), we can add a little computer icon and when it's a data storage attribute, we can give it a small document icon.
