The way I do this lesson depends on the status of other objectives. There is an ambiguity in the spec. Claim that AU smallest level that can be tracked is not true. The smallest level that can be tracked is the objective. Intent is that it is an implied functionality of the CMI system.
Objective information can come in from other AUs.
All we are providing is a convenient persistance store for some pieces of lesson data and has nothing to do with objectives. That is a mislabel. This is coming as a surprise to many of use. I build a big course with an object to use a mouse in an Excel course. Next takes a Word course with an objective to use a mouse.
