Now that the T-Engines provide parity with in process legacy transforms and metadata extract, the legacy transform code is now being removed. This will allow the documentation to be greatly simplified and a number of libraries to be removed.
Custom legacy transforms need to be moved to T-Engines. ACS 6 still provides a version where both may be run in parallel. New versions of the document transform engine (DTE) and media management (MM) are planned for ACS 7.
