Operation definition table (ODT)
An operation definition table (ODT) defines how each operation is
applied to an instance of the object class.

column 1: operation-
a keyword name for an operation. Can be one of:
get, replace, replaceWithDefault, add, remove, create, delete,
action, filter, list.
(create, delete, and action can only be used with
object type, and filter with attribute type - see column 3).
column 2: procedure-
name of (Tcl) or pointer to (C/C++) a function.
More than one operation can share a called procedure.
column 3: target-
can be: object or attribute. Identifies what is to be
acted upon by the procedure: if ``object'', the procedure will
be called once, and all attributes specified on the command
line must be processed; if ``attribute'', the procedure
will be called once per attribute per object on the command
line (this allows each attribute to be handled
individually). Operations performed on object must change
the object without errors or leave it unchanged; operations
on attributes will be done regardless of the success of
preceding or following calls.
In the example, both the operations replace
and replaceWithDefault
apply the function user_set to an attribute.
