Schema Structure Question

In the schema, how do you indicate that at least one item is required (A,B
or C), but also allow for some ("A and B" OR "B and C", etc.) items or all
items(A,B, & C) to be present in the xml? 
We've messed around with the <xs:choice>, <xs:all> ,minOccurs and maxOccurs,
but we can't get the right combination? Any ideas? Thanks.
