To answer my own question:
<f:facet name="document">
<h:panelGroup>
<h:commandLink immediate="true"
styleClass="#{t.nodeSelected ? 'documentSelected' : 'document'}"
actionListener="#{t.setNodeSelected}"
rendered="#{!t.nodeSelected}">
<h:graphicImage value="/images/document.png" border="0"/>
<h:outputText value="#{node.description}"/>
<f:param name="docNum" value="#{node.identifier}"/>
</h:commandLink>
</h:panelGroup>
</f:facet>
