list of time/dates and the AOM

From the ADL spec

4.4.6 Constraints on Dates, Times and Durations
Dates, times, date/times and durations may all be constrained
in three ways: using a list of values, using intervals,
and using patterns

However, the C_DATE, C_TIME etc classes for the AOM
only have a 'range' slot and not a 'list' slot. In constrast, the
C_INTEGER, C_REAL have both a 'range' and a 'list'.

Is there a different way of representing lists of
dates in AOM?

We have never implemented lists of dates, and it is another thing that
no-one has asked for. But on this one, it seems to me that it would be
more consistent to actually add it. What do others think? One thing to
keep in mind is that literal dates are very unlikely to turn up in
clinical archetypes - they never have so far. All date/time constraining
is done via the patterns, which in the AOM corresponds to those boolean
flags you see.
