To me it makes little sense for MDEL and ADEL to have "values", especially
since string comparisons should be "locale dependent".

My thought was for them (or new fields - possibly less confusing?) to be
binary flags that specify whether to force monitor() to post .VAL on every
record process.

These fields would default to 0="don't force", so existing databases would
produce the existing behavior from the modified records.

Or am I missing something else ?
