I am very close to having a Macro/XSLT create a drop down navigation menu. (I am new to XSLT)

Using the following XSLT, I am unable to get the "Home" node added to the navigation menu.  How is it that I can add the Home link like the default 

My desired HTML is as follows:

<nav>
    <ul>
        <li ><a href="/">HOME</a></li>
        <li><a href="#">Link 2</a>
            <ul>
                <li><a href="#">Link 2.1</a></li>
                <li><a href="#">Link 2.2</a></li>
                <li><a href="#">Link 2.3</a></li>
            </ul>
        </li>
        <li><a href="#">Link 3</a></li>
    </ul>
</nav>

My current XSLT is as follows:

<xsl:output method="xml" omit-xml-declaration="yes"/>
<xsl:param name="currentPage"/>

<!-- update this variable on how deep your site map should be -->
<xsl:variable name="maxLevelForSitemap" select="3"/>

<xsl:template match="/">
    <nav> 
        <xsl:call-template name="drawNodes">  
            <xsl:with-param name="parent" select="$currentPage/ancestor-or-self::* [@isDoc and @level=1]"/>  
        </xsl:call-template>
    </nav>
</xsl:template>

<xsl:template name="drawNodes">
    <xsl:param name="parent"/> 
    <xsl:if test="umbraco.library:IsProtected($parent/@id, $parent/@path) = 0 or (umbraco.library:IsProtected($parent/@id, $parent/@path) = 1 and umbraco.library:IsLoggedOn() = 1)">
        <ul>
            <xsl:for-each select="$parent/* [@isDoc and string(umbracoNaviHide) != '1' and @level &lt;= $maxLevelForSitemap]"> 
            <li>
                <a href="{umbraco.library:NiceUrl(@id)}"><xsl:value-of select="@nodeName"/></a>  
                    <xsl:if test="count(./* [@isDoc and string(umbracoNaviHide) != '1' and @level &lt;= $maxLevelForSitemap]) &gt; 0">   
                        <xsl:call-template name="drawNodes">    
                            <xsl:with-param name="parent" select="."/>                </xsl:call-template>  
                    </xsl:if> 
            </li>
            </xsl:for-each>
        </ul>
    </xsl:if>
</xsl:template>
<xsl:template name="drawLevel1">
</xsl:template>

The default umbTopNavigation uses the following to add the Home link, but i get an error when trying to add it after the opening <nav>:

       <li class="home">
         <xsl:if test="$currentPage/@id = $currentPage/ancestor-or-self::* [@level=$level]/@id">
             <xsl:attribute name="class">home current</xsl:attribute>
         </xsl:if>
         <a href="/">Home</a>
       </li>

Any thoughts?
