integer intervals

According to ADL spec 4.4.2.2, intervals of integer values
can be combined using the semi colon character as follows;

critical_range matches {|5..9; 101..110|}

Yet, the AOM definition for C_INTEGER only allows one
range to be specified. Should the AOM be extended
to allow multiple integer ranges or is this syntax
deprecated?

ha! Good question. I think we thought this might be a nice feature in
ADL when we first put it in (ages ago), but in fact, there has never
been a single use for it in medicine, and it seems hard to find any use
for it. If we stick to the informal openEHR dictum that there should be
at least one use case for any feature in openEHR, we would remove it
from ADL rather than further complicate the AOM.

thoughts?
