I was not able to find a "table2node" function ie
nodes.FromTableToNodeButItnotExists(t)
indeed, that has a low priority
BTW,
Am I wrong if I say that this serialization is an alternative form for a pdf
" box " ?
wrong indeed, it's a table representation of a node list (tex's internal 
representation of a box)
