Use Manor 'n Rock JSF HTML components. mriem mriem@manorrock.org Community: Java Enterprise
I am currently working hard to make it possible to use almost all of the HTML 4 strict elements in a JSF way. See for a work-in-progress demo: http://www.manorrock.com/demo/jsf/html/heading.html.

If you want to try it out for yourself, you can either download the necessary JAR files from our Maven 2 repository, or you can use Maven 2 and specify a dependency on the library like this: 
    <dependencies>
        <dependency>
            <groupId>com.manorrock.jsf.html</groupId>
            <artifactId>com-manorrock-jsf-html</artifactId>
            <version>1.3</version>
        </dependency>
    </dependencies>
    <repositories>
        <repository>
            <id>manorrock</id>
            <url>http://repo.manorrock.com/</url>
        </repository>
    </repositories>
Note: since this is a work-in-progress I will keep updating and posting small blog entries explaining what my progress on this library is.

And beyond that you will need to define the taglibrary to use the tag as well. The code below shows you how this is done for this taglibrary.
