  Looks ok to me. One thing i would do: Leave out the 'out' attribute
  of the root node (which probably should designate the root of the
  graph). It does not really fit to the rest of the file. The XML
  describes completely what the graph looks like already. The 'out'
  attribute seems to be different; it seems to describe how to USE the
  graph instead of how it looks. But for this a single attribute is
  not enough anyway. For example, i sometimes use gegl for splitting
  an image into the channels R, G and B, so i have three root nodes,
  so there would be no useful single attribute to use as a root. And
  because i do not have a better idea at hand for how this should be
  included in a serialized format (if it should be included at all),
  i would leave it out.
