In the section that describes how UAs are to handle <object>, right?

How is this different from any other case where there are authoring 
conformance requirements?  In all such cases UAs need to know what to do 
with web pages that violate said requirements (in this case by adding a 
'classid' attribute).

This attribute was present in HTML4 and its behavior only needs to be 
defined to handle legacy content.  Authors of HTML5 documents must not 
(in RFC terms) use it if they want to claim conformance.  UAs must (in 
RFC terms) do certain things with it to claim conformance.

Probably because no one actually implements it?
