+SEQUENCE_NUMBER
+| java.lang.Integer
 | Usually a sequence number with a group of messages with a `SEQUENCE_SIZE` but can also be used in a `<resequencer/>` to resequence an unbounded group of messages.

-| `java.lang.Long`
+| IntegrationMessageHeaderAccessor.
+EXPIRATION_DATE
+| java.lang.Long
 | Indicates when a message is expired.
 Not used by the framework directly but can be set with a header enricher and used in a `<filter/>` that is configured with an `UnexpiredMessageSelector`.
