I disagree. Use of these parameters are definitely *not* specific to a
particular website, and, in fact, may require specific semantics in a UA. At
present, HTML5 states "User agents must not derive any implementation
behavior from these attributes or values. Specifications intended for user
agents must not define these attributes to have any meaningful values." In
contrast, the intended use of param is precisely to define meaningful values
for which UAs derive implementation behavior.

The fact that param is defined on object, and made use of regularly in the
manner I describe, and since it is the intent that audio and video elements
supplant the use of object, it is necessary to retain this usage or provide an

Oh? Why not? There is nothing in the definition of audio or video that preclude
its use. There are no restrictions placed by HTML5 on the media type referenced
by these elements. Since swf and silverlight can represent audio and video
content, why shouldn't they be reasonable examples. In any case, the problem
described here is independent of the examples, and stands on its own without
requiring use of these particular formats.
