unit in the first string can be reserved only if each pattern of units
whose names are in the second string is not reserved. This is an
asymmetric relation (actually @samp{exclusion_set} is analogous to
this one but it is symmetric). For example, it is useful for
description that @acronym{VLIW} @samp{slot0} can not be reserved after
@samp{slot1} or @samp{slot2} reservation. We could describe it by the
following construction
this one but it is symmetric). For example it might be useful in a
@acronym{VLIW} description to say that @samp{slot0} cannot be reserved
after either @samp{slot1} or @samp{slot2} have been reserved. This
can be described as:

@smallexample
(absence_set "slot2" "slot0, slot1")
(absence_set "slot0" "slot1, slot2")
@end smallexample

Or @samp{slot2} can not be reserved if @samp{slot0} and unit @samp{b0}
