 From the top of my head, you need a CoreSession because you need a 
reference on the SchemaManager which is hold by the Session (in fact, we 
use an OperationContext, which contains a Session).

The Partition will manipulate indexes, and for that, we need the 
SchemaManager, as it is the only place we have information about 
AttributeType names and OIDs, as Index are referring AT names or OID.

Now, you should not need the DirectoryService instance to query the 
SchemaPartition.

I have to check what could happen if you pass a null value as the 
CoreSession for this partition...
