Newbie: XLST 1.0 node-set variable lookup by position?

Trying to write an XSLT 1.0 template that will create elements from the Filemaker FMPXMLRESULT METADATA/@NAME attribute. Here's sample XML:

<?xml version="1.0" encoding="UTF-16" ?>
<FMPXMLRESULT xmlns="http://www.filemaker.com/fmpxmlresult">
<METADATA>
    <FIELD EMPTYOK="YES" MAXREPEAT="1" NAME="Type" TYPE="TEXT"/>
    <FIELD EMPTYOK="YES" MAXREPEAT="1" NAME="Level" TYPE="TEXT"/>
</METADATA>
<RESULTSET FOUND="2">
    <ROW MODID="18" RECORDID="28133">
        <COL><DATA>O1</DATA></COL>
        <COL><DATA>L1</DATA></COL>
    </ROW>
    <ROW MODID="5" RECORDID="28153">
        <COL><DATA>D12</DATA></COL>
        <COL><DATA>L1</DATA></COL>
    </ROW>
</RESULTSET>
</FMPXMLRESULT>

And here's my XLST progress so far:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fmp="http://www.filemaker.com/fmpxmlresult" exclude-result-prefixes="fmp">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="no"/>

<xsl:variable name="labels" select="fmp:FMPXMLRESULT/fmp:METADATA/fmp:FIELD/@NAME"/>

<xsl:template match="fmp:FMPXMLRESULT">
    <FMPXMLRESULT xmlns="http://www.filemaker.com/fmpxmlresult">
        <PLAN>
            <xsl:for-each select="fmp:RESULTSET/fmp:ROW">
                <Sign>
                    <xsl:for-each select="fmp:COL">
                        <xsl:element name="{$labels[position()]}">
                            <xsl:value-of select="fmp:DATA"/>
                        </xsl:element>
                    </xsl:for-each>
                </Sign>
            </xsl:for-each>
        </PLAN>
    </FMPXMLRESULT>
</xsl:template>

</xsl:stylesheet>

My trouble is in line 13:

<xsl:element name="{$labels[position()]}">

Where position() doesn't relate to the position of fmp:COL, and likely is meaningless the way I've used it.

What I'd like to reference is the current fmp:COL element in the xsl:for-each loop, but I suspect that this can't be obtained in XLST 1.0 given the way I'm approaching it.

Does anyone have suggestions or pointers on how to proceed?

Many thanks!
