JSF 2.2 added new improvements to support HTML5 features. The two most prominent features for HTML5 support are HTML5-friendly markup and pass-through attributes.
HTML5-friendly markup allows us to develop our JSF views using HTML5 tags, as opposed to JSF-specific tags. In order use these tags, we need to include the http://xmlns.jcp.org/jsf namespace on our page and specify at least one of the tag attributes with one of the attributes defined in this namespace.
In this section, we will rewrite the application we developed in the Developing our first JSF application section earlier in this chapter to utilize HTML5-friendly markup.
To use HTML5-friendly markup with NetBeans, we need to create a web application project from the Java Web section and select JavaServer Faces as a framework for our application as usual. When adding pages to our application, we need to select the XHTML file type from the Web category.
