The DOM tree version needs to be changed each time the DOM tree changes. Do you
have any specific non-obvious examples that should be documented?

The DOM tree version is used to invalidate HTMLCollection caches and
XPathResult, so any modification that can affect either should change the
version. That's easy to discover by searching through WebCore code.
