HTML5 option missing in the renderHTMLForm component

[vidus]

In the LiveCycle Workbench ES4 with Service Pack 1 in the Process Properties view for component called renderHTMLForm, I only see HTML4 option but not the HTML5 option.

Is there something missing from the component? Do I need to import another component for HTML5? Is there HTML5 rendering of a form component available in ES4 with Service Pack 1 in the LiveCycle Workbench?
