Nothing needs to happen to them.
ENML is a markup language, so what's being store is essentially text. Backend storage and processing does NOT need to change
What you get using TinyMCE (or any embedded platform-independent editor) is a consistency across platforms at the GUI (Web, Windows or MAC). I use Windows and Web clients, and I'm now LOSING functionality and getting an inconsistent user experience
By extending ENML to support HTML (created by TinyMCE) you also get a migration path as existing client would still work
P.S when you next reply to this thread, bear in mind y
