I don't like the idea of modelling link traversal as grove mutation.
Suppose I have an XML editor and an XML document with a SHOW=INCLUDE link.
We can imagine two distinct operations:
a) traverse the link, and
b) change the document, replacing the link element by the linked-to resource.
I would suggest it is (b) rather than (a) that is appropriately modelled by
mutating the grove.
