SWF macro generates HTML tags for params without closing sign

The SWF macro produces HTML code that does not closes the tags for param attributes.
The following is the current code produced for this macro:

%

<object classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,45,0" width="640" height="480" id="installingZemucan">
<param name="movie" value="http://www.youtube.com/v/3W0GvjrPFj4&hl">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="loop" value="0">
<param name="play" value="true">
<param name="allowScriptAccess" value="sameDomain"><embed src="http://www.youtube.com/v/3W0GvjrPFj4&hl" width="640" height="480" loop="0" play="true" quality="high" allowScriptAccess="sameDomain" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" menu="false">
</embed>
</object>

But the correct code should be:

<object classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,45,0" width="640" height="480" id="installingZemucan">
<param name="movie" value="http://www.youtube.com/v/3W0GvjrPFj4&hl" />
<param name="quality" value="high" />
<param name="menu" value="false" />
<param name="loop" value="0" />
<param name="play" value="true" />
<param name="allowScriptAccess" value="sameDomain" /><embed src="http://www.youtube.com/v/3W0GvjrPFj4&hl" width="640" height="480" loop="0" play="true" quality="high" allowScriptAccess="sameDomain" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" menu="false">
</embed>
</object>

I attached the patch that adds the final slashes for the params.
