"This specification presents the information set as a tree for the
sake of clarity and simplicity.." (verbatim, from Infoset, Last
"Tree" is a widely used term among computer scientists, logicians,
mathematicians, and so forth. The quintessence of XML is that it's a
linear syntax for labelled trees. (Other characterizations are
possible, of course.) The tree view is the key to the superiority of
CSS and XSLT as an abstraction mechanism over text-macro based markup
languages (like TeX/Latex).

Would you call page numbers "page information items"? The information items

No, I'm concerned that DOM, XPATH, and INFOSET do not turn out to be
essentially the same model. That would be a great shame. Better get it
