Any hope of the Zoho Writer application turning into an HTML5 based editor instead of HTML4?

Any hope of the Zoho Writer application turning into an HTML5 based editor instead of HTML4?

I would like to add customer formatting XML tags and style those tags in an editor. Is there any chance this functionality may be added to Zoho writer? instead of just <H1> For a headline, I want to have <HeadBold> inserted when I choose a style from the menu.
