we have large comment fields in there where our users wrap text in html formatting tags like < b > or < u > etc so they can have more control over how the text displays in the finished out put
that gave me a monumental headach but thanks to the BIP elfs over at Oracle we have a solution . if you adjust your tag name to match
<?html2fo: elementname?> it does the trick nicely and displays the html formatting
thank you oracle that one really helped out
