If B<Table> is set to I<true>, I<Instance> is interpreted as an SNMP-prefix
that will return a list of strings. Those strings are then used as the actual
type-instance. An example would be the C<IF-MIB::ifDescr> subtree.

If B<Table> is set to I<false> the actual string configured for I<Instance> is
copied into the value-list. In this case I<Instance> may be empty, i.E<nbsp>e.
