What is it supposed to be bound to in the following case (i.e. when invoking error() without any description string): <xsl:try select="error(QName('ns', 'code'))"> <xsl:catch> <xsl:value-of select="$err:description"/> </xsl:catch> </xsl:try> Note that XQuery 1.1 defines the equivalent variable (in its own grammar) to be of kind xs:string?, so optional. My humble opinion is that XQuery is correct here. 36965 1 mike 2010-07-16 16:40:09 +0000 Agreed, this needs to be fixed. (Not formally discussed by the WG, but discussed by some WG members after the close of the meeting). 42987 2 mike 2010-12-02 11:46:06 +0000 Change applied.
