HTML compliant SWF markup

I would like to be able to use IMCE to get my files into the SWF markup, so [swf file="xxx"] is out, but &;lt;swf&;gt; is out too, since it isn't valid HTML.

Would it be possible to shift to an HTML SPAN with the value of the CLASS attribute set to "swf"? Then I could create a BUedit button, say, to get to the file via IMCE. Thanks!

NOTE I debated whether this is a feature or a bug, but I came down on the side that anything that produces invalid HTML markup is a bug. If I'm wrong, please feel free to reclassify as a feature.
