we no longer treat body tags differently, so if you want add a transparent markupcontainer to your basepage and attach it to your body tags. then add attribute modifiers to that container.
with the advancement of javascript event handlers people dont use the body tag for this purpose any longer. also we did have support for this in the headercontributor but the unload events are very shoddy and so we decided not to provide it since we did not want to be bombarded with "why does my onunload event dosnt fire" emails. unload events are problematic because some browsers dont implement at all, others only if you navigate a certain way, etc, etc. -igor On Sat, Mar 29, 2008 at 11:46 AM, Zach Cox <[EMAIL PROTECTED]> wrote: > > Seriously?
