The other two provide begin-commit/abort. They give isolation through an MRSW lock - multiple-reader OR one writer semantics.
Any writer locks out readers but the isolation contact of begin-commit/abort is provided. That worse that TIM (Transaction In Memory/TxnMem).
But any code using transactions should be able to use the general daatsets for execution time transaction isolation.
