I'm having trouble making a customization to olink generated text. I want to remove "the section called" from olinks to sections. Can someone point out errors in my method?

To troubleshoot, I have reduced my customization layer to only what I see in: http://www.sagehill.net/docbookxsl/CustomXrefs.html

Here's my stylesheet. It's importing version 1.71.1 of the stylesheets.

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

<xsl:import href="http://server.name.com/techpubs/xslt/docbook-xsl/html/chunk.xsl"/>

<xsl:param name="local.l10n.xml" select="document('en.xml')"/>

</xsl:stylesheet> *******

I have placed an entire copy of common/en.xml from version 1.71.1 of the stylesheets in the directory with my customization layer. In that copy, I have replaced every instance of "the section called" with "the FOO called." I made no other changes.

I publish my DocBook content, which is version 4.3, using Saxon 6.5.3. Here is the command with the parameters I am using:

******* java com.icl.saxon.StyleSheet \ oq/xml/MyDocBookContent.xml \ test.xsl \ base.dir=oq/html/test-results/ \ use.extensions=1 \ target.database.document="../../olinkdb-html.xml" \ current.docid="validationoqtr" *******

The resulting HTML looks great, with live olink cross-references. But they are not affected by my alteration of en.xml and still read "the section called."

What am I missing? I know Saxon is finding my copy of en.xml because if I change its filename, Saxon complains that it cannot be found.

Thanks for your help.
