Referencing original root when using document function

Hello all,

I have a stylesheet in which a lookup table is defined
e.g.
<par:paramfields>
	<par:paramfield value="value1"/>
	<par:paramfield value="value2"/>
</par:paramfields>

I walk through each of these values:

<xsl:for-each select="document('')/*/par:paramfields/par:paramfield"/>

For every value I want make a transformation for which I use data of the
original xml document. So I need e.g.

<xsl:for-each select="document('')/*/par:paramfields/par:paramfield">
	<xsl:variable name="value" select="./@field"/>
	<xsl:apply-templates select="/traps/trap[@type=$value]"/>
</xsl:for-each>

However this doesn't work. How to I indicate in the Xpath expression, that I
want to use my original document again ?

Kind regards,
Ismaël
