I'm trying to insert a release number into my HTML title tag...

Title: I'm trying to insert a release number into my HTML title tag...

I set up the params for release number:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:d="http://docbook.org/ns/docbook" xmlns:exsl="http://exslt.org/common" xmlns="http://www.w3.org/1999/xhtml">

        <xsl:import href="">

        <xsl:param name="product.div.title"> Jack and Jill Cloud Product - </xsl:param>

<!-- test of insertion of release number -->

<xsl:param name="product.rel.number"> 1.0.1 </xsl:param> -->

        <xsl:param name="product.copyright.string" />

    

</xsl:stylesheet>

then, in webhelp-book-base.xsl - I try to insert "product.rel.number:"

<xsl:template name="head.content">

  <xsl:param name="node" select="."/>

  <xsl:param name="title">

    <xsl:apply-templates select="$node" mode="object.title.markup.textonly"/>

  </xsl:param>

  <title>

    <xsl:value-of select="$product.div.title" />

        <!-- test of insertion of release number -->

        <xsl:value-of select="$product.rel.number" />

    <xsl:copy-of select="$title"/>

  </title>

  ...

  

  However, in the build I get this compile error:

  

[java] Error at xsl:value-of on line 94 of file://///publishing/hudson/jobs/build-main-documentation/workspace/serverdoc/WorkingDoc/main/publishing/docbook-xsl-customization/webhelp-book-base.xsl:

[java]   Variable product.rel.number has not been declared

[java] Transformation failed: Failed to compile stylesheet. 1 error detected.

If I remove the "product.rel.number" attempt, the build goes back to working like before (Producing a title tag with product name and book title

I’m not sure how I would achieve the result I want in the built HTML:

<title xmlns:d="http://docbook.org/ns/docbook">Jack and Jill Cloud Product - 1.0.1 - Jack and Jill go up the hill</title>
