We need to switch the document in the content frame, but we cannot
switch the item details, otherwise the LMSFinish() call (that *must*
be triggered by the SCO when it unloads) will use bad values. However,
we need to load the new asset's context once the SCO has unloaded
(4) sco switching to sco
We don't need to switch nor commit, LMSFinish() on unload and
LMSInitialize on load will do the job
In any case, we need to change the current document frame.
These cases, although clear here, are however very difficult to implement
