XSLT stylesheet parameters in imported stylesheets

Question

Is it possible to assign a value to a parameter of an imported stylesheet?

I was expecting something like

<xsl:import ... >
  <xsl:with-param ... 
</xsl:import>

but that is not allowed.

Also tunnel="yes" is forbidden in stylesheet parameters.

Try this:

main.xsl

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:import href="import.xsl"/>

  <xsl:variable name="param" select="'some-value'"/>

  <xsl:template match="/">
    <xsl:call-template name="foo"/>    
  </xsl:template>

</xsl:stylesheet>

import.xsl

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output omit-xml-declaration="yes" indent="yes"/>

  <xsl:param name="param" select="'default'"/>

  <xsl:template name="foo">
    <out><xsl:value-of select="$param"/></out>    
  </xsl:template>

</xsl:stylesheet>

An xsl:variable in an importing stylesheet can override an xsl:param in an imported stylesheet, and this effectively sets the value of the parameter.
