+If you are writing this into XSLT file, you need to format it like this:
+<code>
+  <xsl:template name="addGoogleTracking">
+    <xsl:variable name="trackid">UA-xxx</xsl:variable>
+    <!-- Global site tag (gtag.js) - Google Analytics -->
+	<script async="async" src="https://www.googletagmanager.com/gtag/js?id={$trackid}"><xsl:text> </xsl:text></script>
+	<script>
+	  <xsl:text disable-output-escaping="yes">
+	  window.dataLayer = window.dataLayer || [];
+	  function gtag(){dataLayer.push(arguments);}
+	  gtag('js', new Date());
+	  gtag('config', '</xsl:text><xsl:value-of select="$trackid"/><xsl:text disable-output-escaping="yes">');</xsl:text>
+	</script>
+  </xsl:template>
+</code>
+===== Adding and using new servlet params =====
+To make this work I have modified the java code to store any initParams mentioned in the servlet definition (in servlets.xml) in the config_params HashMap. This gets passed to the transformer when it does the page transformation, so all of these get passed in as parameters. You can access them by declaring
+<xsl:param name="param-name"/> at the start of web/interfaces/default/transform/gslib.xsl along with the other predefined ones.
+<code>
+  <!-- some global parameters - these are set by whoever is invoking the transformation
+  Any servlet init parameters can be accessed by adding a param here-->
+  <xsl:param name="interface_name"/>
+  <xsl:param name="library_name"/>
+  <xsl:param name="site_name"/>
+  <xsl:param name="use_client_side_xslt"/>
+  <xsl:param name="filepath"/>
+  <xsl:param name="google_tracking_id"/>
+</code>
+Now that this has been implemented, instead of hard coding the tracking id in the xslt file, you can specify it as an initParam to a servlet (therefore each servlet can have a different one if need be)
+In web/WEB-INF/servlets.xml, add an init-param like the following to the main library servlet (specifying of course, your actual google id):
+<code>
+	<init-param>
+	  <param-name>google_tracking_id</param-name>
+	  <param-value>UA-xxx-1</param-value>
+	</init-param>
+</code>
+You will need to restart the server for this to take effect.
