A good XHTML 1.1 valid way for embeding flash/java/etc object is bu 
using a template sort of like this. (This is a minimal way)

<object type="mime-content-type" data="path/to/file.class">
<param src="path/to/file.class" />
</object>

That will work on IE, Netscape and Mozilla. Use the data attribute not code.
