<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
id="${application}" width="${width}" height="${height}"
codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab">
<param name="movie" value="${swf}.swf" />
<param name="quality" value="high" />
<param name="wmode" value="transparent" />
<param name="allowScriptAccess" value="sameDomain" />
<embed src="${swf}.swf" quality="high" bgcolor="#869ca7"
width="${width}" height="${height}" name="${application}" align="middle"
play="true"
loop="false"
allowScriptAccess="sameDomain"
type="application/x-shockwave-flash"
pluginspage="http://www.adobe.com/go/getflashplayer"
wmode="transparent">

"align", "middle",
"id", "${application}",
"quality", "high",
"wmode", "transparent",
