Yes - the Cron schema is probably not the best schema.

It was designed to be easy to fit most things into one line.

It can express pretty much everything imaginable. But it's not designed to do that easily.

Maybe it'd be better to come up with a schema that's better suited for expressing non-trivial crons - and converting that to & from crontab format.

English is also not the best language for expressing this type of thing...
