Subject: Re: AW: AW: [xsl] use preceding element or self From: David Carlisle <davidc@xxxxxxxxx> Date: Fri, 29 Apr 2005 11:50:15 +0100 |
Oh in addition to my earlier comments, I think the meaning of a predicate [ 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.
