    Description

      Systems that need to implement "read your own writes" for uncommitted storage transactions are currently implemented as decorations on the OperationContext. To be able to support multi-document transactions and SideTransactions code needs to manually attach/detach the decoration from OperationContext in the TransactionParticipant.

      If we instead had the RecoveryUnit decorable we can build this handling into the WriteUnitOfWork::RecoveryUnitState used by the TransactionParticipant
