I am not sure why you get that error.
When I try this XML document

<foo bbox="1,2,3,4"/>

against this XSLT

<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   version="2.0"
   xmlns:xs="http://www.w3.org/2001/XMLSchema">

   <xsl:template match="foo">
     <xsl:variable name="bboxTokens" as="xs:string*" 
select="tokenize(@bbox, ',')"/>
     <xsl:variable name="bboxWidth"
                  as="xs:decimal"
                  select="xs:decimal($bboxTokens[3]) - 
xs:decimal($bboxTokens[1])"/>
     <xsl:value-of select="$bboxWidth"/>
   </xsl:template>

</xsl:stylesheet>

then it runs fine with Saxon 9 and AltovaXML tools 2009.
