Thanks very much. I should have said we are on 4.2. I'll assume that Mike's comment that "It looks to me like doc-available($uri) is equivalent to xdmp:exists(doc($uri)) now" applies to 4.2 also and not just 5.0 unless I hear otherwise...not sure how I would verify that myself. I don't have access to prod so that's why I can't simply test this. Thanks again.
