You'd need to read my articles on the 2002 changes available at
http://www.publishermvps.com . Filtered html and Rich Output (you called
unfiltered) aka Round-trippable html were introduced in the 2002 version.
The coding engine that debuted in 2002 and remains in 2003, is completely
different from the 2000 (and prior) version. Meaning the concept of filtered
doesn't exist in 2000. 2003 does retain round-trippable (you called it
unfiltered) html, but it is several times heavier then the filtered. Hence
the meaning of "filtered". The filtered output of 2003 is the leanest code
possible with Publisher. Your option for slow-loading pages is to rethink
your design layout. Meaning less is more.
