This attribute is migrated to the AtmTmProv group.
This attribute specifies the holding priority of this connection. In a
situation where the link bandwidth fluctuates, such as over an IMA
link, holding priority is used to determine which connections are
held and which are released. Holding priority 4 connections are the
first to be released. Holding priority 0 connections are the last to be
released. This value provisioned in the Vcd or Vpd may be
overridden by certain applications, for example Vcc Test, which run
over this connection. The default holding priority for a provisioned
connection is higher then default holding priorities for dynamic
(SVC) connections.
