4578 2007-05-24 09:42:44 +0000 [FS] Possible error in filter expression normalization rules 2007-10-04 07:33:43 +0000 1 1 1 Unclassified XPath / XQuery / XSLT Formal Semantics 1.0 Recommendation PC Windows NT CLOSED FIXED P2 normal --- 1 tim jmdyck public-qt-comments oldest_to_newest 15178 0 tim 2007-05-24 09:42:44 +0000 In 4.3.2 Filter Expressions the rule [PrimaryExpr PredicateList [ fn:last() ]]Expr == let $fs:sequence := [PrimaryExpr PredicateList]Expr return fn:subsequence($fs:sequence, $fs:last,1) doesn't define fs:last. I suspect it should be: [PrimaryExpr PredicateList [ fn:last() ]]Expr == let $fs:sequence := [PrimaryExpr PredicateList]Expr return let $fs:last := fn:count($fs:sequence) return fn:subsequence($fs:sequence, $fs:last,1) 15246 1 jmdyck 2007-05-30 06:44:06 +0000 Yup, I agree. 15285 2 jmdyck 2007-06-05 17:10:56 +0000 Today, the Working Group approved your suggested change, so it will eventually appear in the FS errata document, and also be reflected in subsequent versions of the FS document.
