Error [108]: "there is no attribute X"

[ Hello,
my website uses the <embed> tag to show a webcounter, so the tag has 
some attributes:
src="count.swf" quality="high" bgcolor="#FFFFFF" width="88" height="31" 
type="application/x-shockwave-flash" 
pluginspace="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"

I don't think that this is incorrect and i can't find an alternative :/

So, why is this an error?

Thanks ]
