Both the above CSS stylesheets support ruby, form controls and embedded content (iframe, object, video, etc). However in the case of the input form control, some attributes such as autocomplete, list, maxlength, minlength, etc, are not yet supported.

The "Emulate Web Browser" stylesheet renders the following elements the same way as in a Web browser, at the expense of a less convenient editing: ruby, the select form control and most embedded content elements.

A demo document showing these features is available in XXE_install_dir/demo/xhtml5-objects.html.
