When writing, the 'unique field to be written is determined by the file writer.

When reading, the field indicating the context where any event has to
go is as int. This int is mapped to a Context*  by a separate lookup
table.

As you noticed before, nobody looks at the unique field, which
suggests to me that it is superfluous.
