Regarding your comment in #5369:
Do you want to fix this behaviour?

Description = description ?? ScalarResources.LocalCurrencyType_Description;

@PascalSenn we drop the description deliberately. When you change the name of a scalar you often do so to change semantics.

Think about the string scalar where you now give it a meaning like EmployeeName .... now this scalar does no longer have the semantical meaning it had before and needs a new description.
