It is more reasonable in that case, but it's a slippery slope. Once you
get things that might be attributes and might be elements and might be
some evil geek just making up bad examples on purpose, then it's
virtually impossible to design a deterministic algorithm that meets
human intuition (even if you restrict to just one human). You just have
to a prove to yourself that the algorithm _is_ deterministic and does do
something sensible in at least the well formed xml input case, and for
the rest just, accept what came out.

The editor use case might be an "overwhelming objection" to quote
myself, that says we should be more different than HTML5, but unlike
"well formed xml" it's a rather vague under specified set of documents
for which we want to ensure a "reasonable" parse.

It would be interesting to know how a more "declarative" fix up would
fix that example (to any result) rather than just saying the result is
whatever comes out of the parsing algorithm.
