You may nest items' XML elements, which implies that the outer item is 
the repository parent of the inner item.  But the syntaxes above won't 
work with the parcel loader; you have to explicitly specify itemrefs.  
Only elements with itsName= specified will be created as items, and all 
other elements are processed as attribute assignments upon the 
containing element.

<Parcel itsName="example"
     xmlns="http://osafoundation.org/parcels/core"
     xmlns:cm="http://osafoundation.org/parcels/osaf/contentmodel"
     
xmlns:con="http://osafoundation.org/parcels/osaf/contentmodel/contacts"
     xmlns:this="http://example.org/parcels/example">

     <cm:ContentItem itsName="foo">

        <con:Contact itsName="bar">
            <emailAddress value="example at example.org" />
        </con:Contact>

        <sharer itemref="me:foo/bar" />

     </cm:ContentItem>

</Parcel>

The above would define a Parcel item 'example', with a child 
ContentItem named 'foo', and foo would have a Contact item child named 
'bar'.  bar's 'emailAddress' attribute will be assigned 
'example at example.org'.  foo's 'sharer' attribute will be assigned (an 
itemref) to bar.
