[xsl] JDK 1.4 <> 5.0 transformation compatibility

[Kai Hackemesser <kaha@xxxxxx>]

Hello!

I have the strange case that a xsl transformation (XSL 1.0) output looks 
different between an application running in JDK1.4.2 and JDK 1.5.0. In 
fact there is a part of the output html structure missing. I'm not sure 
what caused that. I'm using the original JDK translation engine in both 
cases and there is nothing like scripting or extensions in the xsl, just 
some grouping using xsl-key and generate-id. Does anybody what 
incompatibilites exist between the JDK versions?

   <xsl:key name="IRNCategory" match="IR/N" use="concat(generate-id(..) , string(Category))"/>
(...)
                   <xsl:variable name="currentIR" select="."/>
                   <xsl:variable name="categories"
                       select="N[generate-id(.)= generate-id(key('IRNCategory', concat(generate-id(.) , string(Category)))[1])]/Category"/>
                   <xsl:for-each select="$categories">
                       <xsl:variable name="category" select="."/>
                       <xsl:call-template name="nCategory"/><!-- This is still displayed in both JDKs -->
                       <xsl:variable name="n"
                           select="$currentIR/N[Category = $category]"/>
                       <xsl:call-template name="handleN"><!-- the output of this template is missing-->
                           <xsl:with-param name="n" select="$n"/>
                       </xsl:call-template>
                   </xsl:for-each>
<!-- template is from other xsl included -->
   <xsl:template name="handleN">
       <xsl:param name="n"/>
               <tr>
                   <td colspan="2">
                       <xsl:for-each select="$n">
                           <xsl:sort select="Year" data-type="number" order="descending"/>
                           <xsl:sort select="Number" data-type="number" order="descending"/>
                           <xsl:apply-templates select="."/>
                       </xsl:for-each>
                   </td>
               </tr>
   </xsl:template>
<!-- Template for N just holds an output of N as html table without any relevant logic-->

Kind regards,
Kai
