So how do you express a reference to the parent node in a path property 
inside Oak Core?

Yup. What I meant is that we may need a way to switch off normalizing.

This might break assumptions on stability of path property values. If 
the client sets a relative path it probably expects it to stay relative, 
so that the path continues to work when the node is moved.
