That's not a bug then, it's a design decision, or more particularly a
question of interpretation of the SAX specification. Does the ContentHandler
specification imply a contract that the sequence of events you pass to it is
well-formed? There's no right answer; but there are ContentHandlers out
there that make that assumption and that fall over in a messy heap if you
pass them two top-level element nodes.
