Defining a relationship between an account and a group. Accounts
corresponding to different products are linked together to create a group
so that group processing can be performed at the group level while
independent processing of the accounts is performed at the account level.
The relationship between a dependent account and the group is specified
by a dependent strategy. A dependent strategy specifies group level
processing options for the account. The relationships between the
accounts and the group are flexible to accommodate changes in the status
of the group cardholders.
