Each store has slightly different semantics wrt draft v published. XML doesn't officially recognize draft
but does hold it in a subdir. Old mongo has a virtual but not physical draft for every unit in published state.
Split mongo has a physical for every unit in every state.
Given that, here's a table of semantics and behaviors where - means no record and letters indicate values.
For xml, (-, x) means the item is published and can be edited. For split, it means the item's
been deleted from draft and will be deleted from published the next time it gets published. old mongo
can't represent that virtual state (2nd row in table)
In the table body, the tuples represent virtual modulestore result. The row headers represent the pre-import
