Re: AW: AW:  use preceding element or self
Oh in addition to my earlier comments, I think  the meaning of a
[ boolean valued-expression]
has changed a bit in the various drafts of XPath2, i can't remember what
saxon 8.2 did.

The tension is between saying [false()] should filter as false because
it's boolean false, or whether [false()] is really [$x] for a non-empty
sequence of values (the value being the boolean false) in which case it
should filter as true as (in Xpath1) Non empty node sets filter as true,
and empty node sets filter as false.
