Actually it really isn't. In fact, the HTML spec defines <object> probably 
better than it defines its other inclusion mechanisms (not that that is 
saying much, given how vague it is about <object>).

The HTML5 spec will unambiguously define inclusion mechanisms for all of 
HTML's various inclusion features, including <img> and <object>, though.

I don't really understand what that means. Is HTML (or XHTML) out of scope 
for WICD? What languages are in scope, if that is so?

How should a CDR UA handle a document with an element that references 
multiple documents, then? It seems like it will be hard to obtain 
interoperability if you do not specify this.

I do not feel this issue is resolved, but as it seems that CDF are not 
targetting Web browsers and Web content authors (which are the communities 
I am concerned about) I retract this and any other objections I may have 
raised on this specification.
