<xsl:variable name="averageLineLength" you have used an as attribute that says this mmust return one value but if $lines has less than two items $lines[last()]/preceding-sibling::node() will be empty, so avg() will get an empty sequence, and so return () so you fail the type check. perhaps select="(round(avg($lines[last()]/preceding-sibling::node()/@length)),0)[1]" woul dbe what you want, returning 0 if there are no lines to average.
