It's always known at compile time which variables are in scope, because xsl:import and xsl:include can be resolved at compile time. Therefore, there's no point in having a run-time test on the existence of a variable, any more than there is in C or Java. Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
