For La Ishá, we did a copy overhaul and rewrote most* of the HTML semantically while re-factoring the .css files. With regards to the Volusion WYSIWYG as well as other WYSIWYG editors, there is inline code that is written into various blocks of copy. We also did a very quick aesthetic adjustment to the nav and content_area.
*There are certain areas which can not be re-written semantically in Volusion. We have no control over that.
