The last set of interfaces implemented by the TSF manager are the 'odd-ball' interfaces that don't really fall into any other logical groups. 

Helpers

The interfaces in this category provide auxiliary services for applications or text services. 

Interface	How to Obtain

ITextStoreACPSink	Passed to ITextStoreACP::AdviseSink
ITfEditRecord	Passed to ITfTextEditSink::OnEndEdit

 

MSAA interoperability

These interfaces were originally created to allow TSF to interoperate with MSAA.  Unfortunately, no 3^rd party developers implemented the MSAA client support needed to make these interfaces work, so at this point, these interfaces are effectively obsolete.
