According to HTML5 spec, the <embed> tag can play a swf file, however, the <object> tag can also play a swf file (though <object is defined in HTML4>).<br>I don't understand why need the <embed> tag , because the <object> tag can support(or embed) many objects such as images, audio, videos,
Java applets, ActiveX, PDF, and Flash.<br><br><br>thanks.<br>
