The Web Services Atomic Transaction (or WS-AtomicTransaction) specification and the Web Services Coordination (or WS-Coordination) specification define protocols for short term transactions that enable transaction processing systems to interoperate in a web services environment. Transactions that use WS-AtomicTransaction have the ACID properties of atomicity, consistency, isolation, and durability.
The specifications can be found at

CICS® applications that are deployed as web service providers or requesters can participate in distributed transactions with other web service implementations that support the specifications.
