After some months spent in various iterations with UVCMS (Moodle Partner) it seems that the IMS-CC import facility is ready to land into 19_STABLE.
So I'm going to commit all their code (/backup/cc whole directory) to CVS now in order to have it under control.
Apart from that dir, there are two small modifications to make in Moodle Core (backuplib + new admin experimental setting), in order to definetively have the IMS-CC enabled. I'll commit them later (surely after 1.9.6 release).
Ciao
