This sample built for the Biztalk 2006 Design Contest shows how a per-instance custom pipeline can be used to set the map name in a message. Then, the message can be mapped dynamically using an Orchestration. This allows for a consistence approach to transformation and exceptions. Set up: Just extract to your C:\ drive and follow the instructions in the Word document.

This sample will also work with BizTalk 2006 and BizTalk 2006 R2.
