Is this a legal XPath Expression?

Hi there

The <xsl:variable> assignment works fine in MSXML3 but not in Saxon 5.51:

<xsl:template match="TR/TD[15]">
		<xsl:variable name="subject"
select=".[not(.=preceding::TR/TD[15]/node())]"/>
		<xsl:if test="$subject !=''">
		<tr>
			<td>
				<a href="{$subject}.html"><xsl:value-of select="$subject"/></a>
			</td>
		</tr>
		</xsl:if>
</xsl:template>

Saxon replies with 'Unexpected token [ beyond end of expression'

If I change the expression to

<xsl:variable name="subject"
select="node()[not(.=preceding::TR/TD[15]/node())]"/>

it works in Saxon.

I understood that . and node() were equivalent.

Thanks

Phil
