Luke, I would say you are using the term "supported" a little losely. If I create a document with sup tags already in it they will be stripped by ezpublish. This is less than desireable. I have paid for the support call and have received the files necessary to get sup tags working. I was dismayed however to find that the code I paid for will not be merged into the next version of ezpublish. This is very diappointing and I hope ezpublish will reconsider including this code.

Would you consider posting the code / information you received to the community as a contribution?
This is in my opinion just about the next best way to making this feature available to the rest of the community without them having to pay for the support call again...
