Writing a style sheet and wanting to test a node value to see
whether it is
numeric or not? (Decides HTML align formatting)
<xsl:if test="string(number(.))='NaN'">
<xsl:attribute name="align">right</xsl:attribute>
</xsl:if>
(or in 2.0, ". castable as xs:decimal" - or xs:integer, xs:double etc if
preferred)
