umm great, IBM has patented the WYSIWG html editor. I'm pretty sure that every single WYSIWG html editor allows a user to enter in non-html (or programming) code & almost every single of these editors have a blank page loaded when you select "new page" that has the basic html head & body tags already there.
what is really interesting is:
"Based on roles-based, multi-level security, certain users of the web site may have access to certain information and others may not"
so basically any single website I've written in the past 3 years that uses php functions & .htaccess can be considered prior art. sheesh.
