Is there a way to control tag useage like in tinymce with the valid elements option? The extra allowed content option seems to be as the name suggests, just a second layer of control.
I would like to restrict the tags to just the basics. I would also like to force some values to my headings, which I accomplished in tinymce like this:
h2[role:heading|aria-level:2]
I searched the documentation, which wasn't to much help at all.
