[xsl] Using saxon-js to run a javasscript function from XSLT at the command line

["dvint@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I'm trying to put this together from various sources on the web and none 
of them seem to be complete. Main piece missing is how to connect the js 
to the stylesheet. I'm just trying to get a simple exsmple working 
before tackling my main problem.

This is my command line. I can't get the xslt3 command to work like the 
examples show, but this gets me there:

node <ptah>/node_modules/xslt3/xslt3.js -xsl:test-js.xsl -s:test-js.xsl

Gives me:

Error XPST0017:
  Static error in XPath on line 20 in _betterXML/test-js.xsl 
{saxon:call('greet', $name)}: Unknown function 
Q{http://saxon.sf.net/}call()
Failed to compile stylesheet

STYLESHEET test-js.xsl

<?xml version="1.0" encoding="UTF-8"?>

    <xsl:sequence select="saxon:call('greet', $name)"/>
  </xsl:function>

  <xsl:template match="/">
    <result>
      <xsl:value-of select="mf:greet('World')"/>
    </result>
  </xsl:template>
 <xsl:stylesheet>


my-functions.js

 // my-functions.js
function greet(name) {
  return "Hello, " + name + "!";
}

Stylesheet and JS file are in the same folder. I'm using the stylsheet 
as the data file as the stylesheet isn't really doing any processing. I 
suspect this isn't correct, but something is needed to connect the 
stylesheet to the JS file like this

<saxon:script src="my-functions.js"/>
