A group has a collection of group entries. Each group entry associates the group with an item. An ItemID identifies a group
entry within its group. The pathname of an item may be used as an alternative to the ItemID when the group entry is created
(see
Section 4.2.4, “DAISItem IDL,? on page 4-15).
In OPC the GroupEntry interface corresponds to the interface IOPCItemMgt.
