So with a Basic XSLT Processor I can do: <xsl:if test="xs:date(@date-of-marriage) gt xs:date(@date-of-death)"> which takes the string values of two attributes, converts each one to a date, and then compares them as dates. But I cannot do a date comparison as: <xsl:if test="@date-of-marriage gt @date-of-death"> which relies on the schema processor annotating these attributes as being of type date. I hope this makes it clearer. Michael Kay
