Concerns about flash and xhtml compliance

Could W3 please include the embed tag and the attributes it uses?  I
would like my site to be both xhtml compliant and have Flash objects
that play on Windows/Macintosh...  The system I found that does not use
the embed tag and includes an alternate image, does not play on Mac.
 
Tested on OS9 and WinXP using Iexplore.
 
Thanks
