Adding Flash content

Can I create a link to a swf file but still conform to CSS (wc3 4.0.1)?

My site didn't like (see below) although I'm not surprised.

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="356" height="82">
<param name="movie" value="images/bedrooms.swf">
<param name="quality" value="high">
<embed src="images/bedrooms.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="356" height="82"></embed>
</object>

Thanks
