The point is not to build a tree of potentially unbounded size (think XMPP). The point is to yield events in a non-blocking way (iterparse() is blocking, which makes it useless for non-blocking applications).

An IncrementalTreeBuilder wouldn't have much point IMO. It is not more costly to accumulate a string and parse it at the end, than to progressively build a growing XML tree.
