I need classifiers MBCs to be visible and usable in Composer.
They've been developped in XIB 211 and need to be available in Composer.
They come from the template MBC located in $CORE_ROOT/example/hierch.

You need to add the criteria labels in the IP -> generic classifier activity -> configuration tab -> specific parameters
For eg, the criteria labels can be like;-

       "To",
       "From",
       "Type",
       "Subject"

(To check you can view the structure of MFC in server component in composer)
if you add the keywords in the IP, the MBC should be visible in the IT.
