This file provides a standardized way of assoc iating alternate associating alternative
from various schemes with
.
At any point in time , an alternate alternative
within a particular scheme will be associated with one and only one
. A

may be associated with zero or
mor e alternate more alternative within a single scheme.
It is important to note that the

|
and it
's
alternate alternative all identify precisely the same real-world object.
