--- Comment #4 from Jim Melton <jim.melton@acm.org> ---
At its F2F meeting on 2012-10-30, the WGs agreed to adopt a version-number
policy that is outlined by the following bullet points:

XQuery processor that implements version "n.m"

* If given a query specifying version "n.m", then evaluate it using
"n.m" rules

* If given a query without a version specification, then evaluate
it using "n.m" rules

* If given a query specifying version "x.y":

- If able to process query strictly as version "x.y", then may do so

- If unable to process query as version "x.y", but "willing and able"
to evaluate query as version "n.m", then
  # may give warning
  # Evaluate using version "n.m" rules

- Otherwise, error

The Editor will wordsmith this policy properly.
