EnumMemberAttribute

The default value.

Only a single instance is relevant for a given point of time.
Typical example would be 'Customer/Firstname'.
The PropertyStream / API-calls should look something like this:
Customer/42/Firstname = 'John' // Set name
Customer/42/Firstname = 'John Martin' // Change name
Customer/42/Firstname.SetInvalid = 2020-03-20 // 'Delete' FirstName

Note that due to intrinsic traits of the PropertyStream concept, history of values will always be available, therefore the name HistoryOnly. (availability of history may of course be limited by any -DataRetention mechanisms used though).
