Extend allowable answers with additional permitted values
Domain Description
In many cases, data elements can be reused but the allowable values need to be extended or restricted. For example, one researcher may want to capture diseases of the nervous system while another may want to capture diseases of the cirulatory system. These both can be captured in the same data element (disease) using the same controlled terminology (ICD-9).
...
However,
...
the
...
list
...
of
...
allowable
...
values
...
is
...
quite
...
different.
...
Furthermore,
...
yet
...
another
...
researcher
...
may
...
want
...
to
...
focus
...
only
...
on
...
certain
...
circulatory
...
diseases,
...
such
...
as
...
those
...
of
...
the
...
heart.
