--- Comment #15 from Michael Dyck <jmdyck@ibiblio.org>  2009-04-28 04:03:56 ---
See Zhen's "first question" in comment #8, specifically the example
    if (fn:true()) then () else 3
This expression can be determined statically to always return an empty
sequence, and so qualifies as a vacuous expression using the definition in
comment #14. However, the intent is that it not be a vacuous expression, which
is allowed by the definition in comment #13.
