GDA: Tables for things which are not objects

[Phil Longstaff]

There are currently 3 tables which handle things which are not objects:

1) slots
2) recurrences
3) tax table entries

One thing that the slot_id field provided was an ordering of the slots 
for a specific object.  For slots, the order isn't important.  Is there 
a reason that that recurrences or tax table entries need to be kept in a 
specific order?  If so, I can still remove the id auto-increment field 
but will need to add an ordering field so that obj_guid won't be unique 
(but will be indexed), but the pair (obj_guid,order) will be unique.
