There's only one kind of tree that's of interest in XDM, and that's the tree of
nodes defined implicitly by the dm:parent relation between nodes. XDM is
talking about this kind of tree (and indeed, this kind of node), and XDM nodes
each belong to exactly one tree of this kind. A "subtree" of this tree is not
itself a tree, because it does not contain a root node; it is an essential
property of a root node that it has no dm:parent.
I wasn't aware that the use of the term "tree" in mathematics differed so
widely from the use of the term in computer science - clearly it's the usage in
computer science that's relevant here, not the usage in mathematics.
