    Hi Jürgen,

    The structure I'm trying to model isn't a tree so in my case a child may
    have many parents.

    The only flattened relationship I need is the children (and possibly
    parents) of a Node, I just don't want to have to access a NodeMap object
    directly to discover them.

    Thanks.
