Ooops!
That should be manytoone! My Bad!
(I did mention it was pseudo code, right?)
<object name="cart>
<id name="uuid" />
<onetomany name="LineItems">
<link to="LineItem" />
</onetomany>
</object>
<object name="Product>
<id name="uuid" />
</object>
<object name="ProductOptions>
<id name="uuid" />
</object>
<object name="LineItem>
<compositeid>
<parentonetomany class="cart" />
<manytoone name="Product" />
<manytoone name="ProductOption" />
</compositeid>
<manytoone name="Product">
<link to="Product" />
</manytoone>
<manytoone name="ProductOption">
<link to="ProductOption" />
</manytoone>
</object>
That should make more sense now :D
