Your recursive call on the template with mode=modify
<xsl:apply-templates mode="modify">
<xsl:with-param name="id1"
select="$newid"></xsl:with-param>
</xsl:apply-templates>
does not set the $curnode parameter. This means it will take its default
value, which is a zero-length string. Doing an apply-templates on a
zero-length string will give you a type error.

What am I doing wrong here?
I think we need more code fragments to see ... nothing strikes me as
incorrect in the two snippets you've given.
If you are using <xsl:with-param/> inside of <xsl:apply-templates/>
(you
don't say if you are using <xsl:call-template or not) make sure you
don't have any built-in templates being triggered between
the processing
of the two templates. If so, the built-in template will
not pass the
node parameter, the template with the parameter declaration
will get
called by the built-in template with no parameters, the
default value
for an empty parameter declaration is string, and you will
have an empty
string passed for the <xsl:apply-templates/>.
But that is just a guess based on your evidence.
I hope this helps.

This is my stylesheet
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:strip-space elements="*" />

<xsl:variable name="maindoc" select="/" />
<xsl:template match="TM">

<xsl:apply-templates select="T" mode="structure1" />
</STR>
</UI>
</xsl:template>
<xsl:template match="T" mode="structure1">
<xsl:variable name="id" select="@Identifier" />
<xsl:variable name="ttm" select="./Type" />
<xsl:variable name="tc" select="@Category" />
<xsl:variable name="uc" select="./Prefs/UC" />
<xsl:variable name="ups" select="./Prefs/UPS" />
<xsl:for-each select="document('lookup.xml')">

<xsl:apply-templates mode="modify" select="/TM/

</xsl:for-each>
</xsl:template>
<xsl:template mode="modify" match="*">

position())"></xsl:variable>
<part class="{name()}" id="{$newid}">
<xsl:apply-templates mode="modify">

</xsl:apply-templates>
<!--xsl:apply-templates mode="structure1"
select="$curnode"
/--> <!-----******* Error on this line here -->
</part>
</xsl:template>
<xsl:template match="Prefs|Type" mode="structure1" />
</xsl:stylesheet>
The error line is indicated above.
Ken, could you please elaborate on what the built-in template rule is
for the situation above? I read the XSLT 1.0 spec, but couldn't fully
understand what it says.
Thanks,
-Farooq.
