In the 2nd Last Call of the W3C XSLT 3.0 specification, almost at the end of section 8.3 "Try/Catch", http://www.w3.org/TR/2014/WD-xslt-30-20141002/#try-catch, there is an enumerated list of additional rules that apply to the catching of errors. Of these, Rule 1 says: "All dynamic errors occurring during the evaluation of the xsl:try sequence constructor or select expression are caught (provided they match one of the xsl:catch elements). - This includes errors occurring in functions or templates invoked in the course of this evaluation, unless already caught by a nested xsl:try. - It also includes errors caused by calling the error function, or the xsl:message instruction with terminate="yes", or the xsl:assert instruction. - It does not include errors that occur while evaluating references to variables whose declaration and initialization is outside the xsl:try" I wrote a small transformation with the purpose of demonstrating the last bullet: <xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xsl:output method="text"/> <xsl:param name="pAmount" select="t"/> <xsl:variable name="vAmount" as="xs:decimal" select="$pAmount"/> <xsl:template match="/"> <xsl:try> <xsl:sequence select="$vAmount"/> <xsl:catch select="-99999999"/> </xsl:try> </xsl:template> </xsl:stylesheet> And I expected that, according to the quoted rule above, the error in initializing the variable "vAmount" would not be caught, because this variable's declaration and initialization is outside of the <xsl:try> instruction. However, the result of the transformation, when run with SaxonEE 9.6.02 is: -99999999 My question: Is this a Saxon bug, or is the specification incorrect, or am I not understanding correctly the rule quoted above. If the last of these is true, could someone, please, provide an example, whose running would demonstrate the 3rd bullet of the rule quoted above? -- Cheers, Dimitre Novatchev
