+* `StreamNameHeader` - The name of the stream the message belongs to, in the format `[aggregateName]-[aggregateId]`.
+* `PlayheadHeader` - The position of the message within its stream.
+* `RecordedOnHeader` - The date and time when the message was recorded.
+* `EventIdHeader` - The unique id of the event.

+* `TagsHeader` - The tags attached to the message (experimental).
 * `ArchivedHeader` - Flag if the message is archived.
 * `StreamStartHeader` - Flag if the message is the first message in a new stream.
