Tree: Child with multiple ParentIds

[GilbertGrape]

Hi,

I have a question.
I am using a Tree with the ModelType Parent, because my data-XML looks like that:

 <Link Id="7" Location="/bla/services/GetParameter.html" Name="GetParameter" Package="blub" ParentId="4" Type="Service">
        <Keywords>
            <Keyword Value="default parameter"/>
            <Keyword Value="version parameter"/>
        </Keywords>
        <Examples />
    </Link>

I use Tree#linkNodes(...) to create the tree.
I don't use DataSources.

Is it, in that case, possible, that one child has various parents? I presume not :(
If so, how would the XML look like then?

Thanks in advance!
