We should 1st create a Jira issue for this, isn'it (maybe there is already one)
? I guess your example is a good base for that using
all adjusters Adrian proposed years="${year}"... millis="${millis}".
Adrian proposed that the field "field=" could be optionnal, so the adjusters
fields, but there must be at least one of them
(including "field=" in them ?) I don't think a such a rule is already used in
minilang.
