this question is about pointless of Partiles in Structure spec.
3.9.6
...
Schema Component Constraint: Particle Valid(Restriction)
...
...
<choice>
One of the following must be true:
2.2.1 {particles} is empty "and the particle within which this <choice> appears has {min occurs} of 0. "
2.2.2 All of the following must be true:
2.2.2.1 The particle within which this <choice> appears has {max occurs} and {min occurs} of 1.
2.2.2.2 One of the following must be true:
2.2.2.2.1 The <choice>'s {particles} has only one member.
2.2.2.2.2 The particle within which this <choice> appears is itself among the {particles} of a <choice>.
in above 2.2.1,
i cannot understand why "and the particle within which this <choice> appears has {min occurs} of 0." is appended...
"{particles} is empty" is not enough?..
anybody can answer me?
