embed tag vil ikke validerer i XHTML transitional

Hvad er der lige galt med dette:

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" style="width:909px;height:280px;"><param name="quality" value="autohigh" /><param name="play" value="true" /><param name="loop" value="true" /><param name="scale" value="showall" /><param name="movie" value="/files/Flash/Cabiheader_v4.swf" /><param name="wmode" value="opaque" /><embed src="/files/Flash/Cabiheader_v4.swf" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" wmode="opaque" style="width:909px;height:280px;"><param name="quality" value="autohigh" /><param name="play" value="true" /><param name="loop" value="true" /><param name="scale" value="showall" /></embed>

Får kæmpe mange fejl på det, men hvis jeg piller embed tag væk, så vises flashen ikke...
