How do we define a parent relationship in an xPDO XML schema? It’s one table, so the notion of primary/secondary and composite/aggregate seems moot.

I’m working on this page:
http://rtfm.modx.com/display/xPDO20/More+Examples+of+xPDO+XML+Schema+Files

Can someone help a brother out here?

Thanks!

From the modResource definition:

<aggregate alias="Parent" class="modResource" local="parent" foreign="id" cardinality="one" owner="foreign" />
<aggregate alias="Children" class="modResource" local="id" foreign="parent" cardinality="many" owner="local" />
