If an item has multiplicity 1..N, then

container is 1..1. Think that was the NDR
conclusion earlier on.
The challenge comes from the other case:
Given that the item has
multiplicity 0..N, should the container be 0..1 or
1..1?
I think in the 1..N case the container element should
have multiplicity 1..1 and the contained element can be minOccurs=1,
maxOccurs=unbounded or whatever.

The attached .zip file shows an example. A person
has 2 parents and zero-or-more siblings. I've modeled this as a Person
(global) element of (complex) type Person. A Person has a (local) Parents
element (minOccurs=1, maxOccurs=1) which in turn has a series of Parent element
(minOccurs=2, maxOccurs=2). A Person has a Siblings element (minOccurs=0,
maxOccurs=1) which in turn has a series of Sibling element (minOccurs=0,
maxOccurs=unbounded).
