I think your definition here is wrong, Paul. "Transclusion" as described by
Nelson would effectively link two groves. You can't copy the nodes into your
own grove, you have to traverse to the grove that contains the transclusion
and then traverse back at the end of it.

The difference between transclusion and inclusion is that the context of the
transcluded content is still retained. In Nelson's application model,
transclusions opened a viewport that was nested inside your document. This
way you could scroll above and below the transcluded content to see its
original context.

But I do agree with your original statement--auto/embed is not node
transclusion.
