What's your goal?  Do you want the content to show up in browsers that 
do not support <object> (not sure what those are; NS4 maybe?)?  Then 
what you have is correct (and yes, I know that does not validate).

If you only care about browsers with <object> support, you can either 
have only a single object element or two nested ones... The reason to do 
nesting is that

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" />

Means "run the ActiveX control with ID 
'D27CDB6E-AE6D-11cf-96B8-444553540000' on the data". If the user is not 
using Microsoft windows, the UA should ignore such an <object> (since 
ActiveX is not available) and use the alternate rendering.  It's good 
practice to make the alternate rendering an <object> that keys off of 
mimetype only (I would say it's good practice to make your _first_ 
<object> key off mimetype only, but I seem to recall IE/Windows not 
supporting that and _requiring_ the ActiveX ID; I would be happy to know 
I am wrong on this point).  Of course the alternate needs an alternate 
rendering too (probably text, or maybe an image).

I think the idea is that the user should be deciding for himself whether 
to open new windows.
