I see. I'm wondering though how practical that will be. Will the
developer who puts the constraint always know the structure of the
Period set to the field (data set by the application user)?
In the case you want it to be validated, you ought to :-)

How would that look like for a Period with several elements set, e.g.
"3 months, 2 days"? Would we need a dedicated member in @ChronoUnitMax
for each value of ChronoUnit (which are a lot)?
What do you mean by a member in @ChronoUnitMax? In my example, I suggest
using unit as a member, leading to unit and value being the only members.
We had a discussion of Duration et al. a while ago, but it petered
out. So we thought we'd add something to the RI to spark a new
discussion. Seems it worked :)
Can´t disagree :-)
