The wM XI Adapter interacts with SAP XI servers. It does not provide XI functionality per se, rather it interacts with it.
As an alternative to XI, you might want to consider the wM SAP Adapter, which interacts with SAP using BAPI, ALE, RFC, and IDocs.
Review the docs on Advantage for information about both of these adapters to help you make an informed decision.
