[4suite] XSL Node-set parameter lost?

[nico]

Hello,

I use 4suite XML 1.0 to compile some docbook files, and have some troubles  
when using some node-sets in template parameters. The original XSL file is  
heavily stripped here to show the problem.

The troublesome is when I do something like this, where the colspec param  
passed to the row template is a node-set:

<xsl:template match="row" mode="newtbl">
   <xsl:param name="colspec"/>

   <xsl:variable name="entries">
     <xsl:copy-of select="entry"/>
   </xsl:variable>

   <i>
     <xsl:value-of select="count($colspec/*)"/>
   </i>
   <xsl:apply-templates select="exsl:node-set($entries)" mode="newtbl">
     <xsl:with-param name="colspec" select="$colspec"/>
   </xsl:apply-templates>
</xsl:template>

<xsl:template match="entry|entrytbl" mode="newtbl">
   <xsl:param name="colspec"/>
   <e>
     <xsl:value-of select="count($colspec/*)"/>
   </e>
</xsl:template>

It crashes when trying to execute the entry template, meaning that  
$colspec is not seen as a node-set:

: Built-in template invoked with params that will be ignored. This message  
willonly appear once per transform.
   self.warning(MessageSource.BUILTIN_TEMPLATE_WITH_PARAMS)

TypeError: $colspec must be a node-set, not a string

If instead of applying templates on a node-set built from the $entries  
variable the entry elements are used, it works fine:

<xsl:template match="row" mode="newtbl">
   <xsl:param name="colspec"/>

   <xsl:variable name="entries">
     <xsl:copy-of select="entry"/>
   </xsl:variable>

   <i>
     <xsl:value-of select="count($colspec/*)"/>
   </i>
   <!--
   <xsl:apply-templates select="exsl:node-set($entries)" mode="newtbl">
   -->
   <xsl:apply-templates select="exsl:node-set(entry)" mode="newtbl">
     <xsl:with-param name="colspec" select="$colspec"/>
   </xsl:apply-templates>
</xsl:template>

Please find attached the XSL stylesheet and an XML file example that  
reproduce the problem. I hope you can help. JFYI it works fine with  
xsltproc.

Regards,
BG
