5.1 Security Considerations for Implementers
The transaction processing protocol that is defined by this specification is intended for use in an environment where all participants are trusted to collaborate in driving transactions toward a final outcome.

Because transaction managers generally communicate with multiple participants simultaneously, this condition represents a denial of service to other participants.
Consequently, implementers are strongly encouraged to take the following steps to ensure that transaction processing occurs in a secure environment:
