Ah yes, thanks - I knew it had to be there somewhere!

And I see that the same rule is present for other kinds of particle as well.

One does wonder why maxOccurs="0" is allowed, if it has to be treated as an
exception to the normal rules. I guess it's analogous to use="prohibited" on
attributes, which also causes some odd anomalies.
