Besides the fact -- as you point out -- that it doesn't solve the
problem, KVP frames aren't actually data model.  I maintain that we
should try not to use them, and if we do, only with good reason; this
doesn't feel like one.

Yup; as I mentioned on -devel, it might be a good thing to fix for a
2.0.{5,6}, so we get a bit of breathing room for 2.{x>0}...

To preempt your question about "how do you tell a broken datafile from
one with simply new tags?", I say: "you don't".  You let XML
well-formed-ness deal with really corrupted datafiles, and you ignore
any tags or attributes that you don't recognize.   If you then ignore
valid future data, fine; if you ignore invalid/broken data, fine.  The
utility of reading a wider set of datafiles is higher than the risk of
reading inconsistent data, with some amount of care taken in the future.
