<nav:iterateInitialNavNodes>
<nav:ifNavNodeInSelectedPath>
<TD nowrap class="chosenTDLevel1">
<nav:navNodeAnchor navigationMethod="byURL"
anchorAttributes="class='chosenOnLevel1'"/>
</TD>
<% if(levels==2) { %>
<nav:storeNavNode/>
<% } %>
</nav:ifNavNodeInSelectedPath>
<nav:ifNotNavNodeInSelectedPath>
<TD nowrap class="unChosenTDLevel1">
<nav:navNodeAnchor navigationMethod="byURL"
anchorAttributes="class='unChosenOnLevel1'"/>
</TD>
</nav:ifNotNavNodeInSelectedPath>
