How to render a custom attribute of <h:outputLink>?

I am trying to implement pinterest's pinit button using a snippet like the one below:

<h:outputLink value="http://pinterest.com/pin/create/button/" class="pin-it-button" count-layout="horizontal">
   <f:param name="url" value="#{beanOne.someMethod}/sometext{prettyContext.requestURL.toURL()}"/>
   <f:param name="media" value="#{beanOne.someOtherMethod}/sometext/somemoretext/#{beanTwo.someMethodTwo}-some-text.jpg"/>
   <f:param name="description" value="#{beanTwo.someOtherMethodTwo}"/>
   <img border="0" src="//assets.pinterest.com/images/PinExt.png" title="Pin It" />
</h:outputLink>

Here are the gotcha's:

Now my question is either one of:

The required markup can be found at http://pinterest.com/about/goodies/ down in the "pin it button for websites" section.

Either use a normal <a> element along with a custom EL function which delegates to URLEncoder#encode().

<c:set var="url" value="#{beanOne.someMethod}/sometext#{prettyContext.requestURL.toURL()}"/>
<c:set var="media" value="#{beanOne.someOtherMethod}/sometext/somemoretext/#{beanTwo.someMethodTwo}-some-text.jpg"/>
<c:set var="description" value="#{beanTwo.someOtherMethodTwo}"/>

<a href="http://pinterest.com/pin/create/button/?url=#{utils:encodeURL(url)}&amp;media=#{utils:encodeURL(media)}&amp;description=#{utils:encodeURL(description)}" class="pin-it-button" count-layout="horizontal">
   <img border="0" src="//assets.pinterest.com/images/PinExt.png" title="Pin It" />
</a>

(note that the class attribute was invalid for <h:outputLink>, you should be using styleClass)

Or create a custom renderer for <h:outputLink> which adds support for count-layout attribute. Assuming that you're using Mojarra, simplest would be to extend its OutputLinkRenderer:

public class ExtendedLinkRenderer extends OutputLinkRenderer {

    @Override
    protected void writeCommonLinkAttributes(ResponseWriter writer, UIComponent component) throws IOException {
        super.writeCommonLinkAttributes(writer, component);
        writer.writeAttribute("count-layout", component.getAttributes().get("count-layout"), null);
    }

}

To get it to run, register it as follows in faces-config.xml:

<render-kit>
    <renderer>
        <component-family>javax.faces.Output</component-family>
        <renderer-type>javax.faces.Link</renderer-type>
        <renderer-class>com.example.ExtendedLinkRenderer</renderer-class>
    </renderer>
</render-kit>
