I think that's the point.  OBJECT is not intended as a replacement for 
server-side includes and should not be used to build a document from sub-
documents that could not otherwise stand on their own.  An embedded HTML 
document is a complete HTML document, not a portion of a document that one 
might include with a SSI.  For including HTML documents, OBJECT is just 
IFRAME with a better name and no targeting.  The two should be presented 
in the same way by a user agent.

If OBJECT is shoehorned into a SSI replacement, you have a major problem 
when you want to include an independent HTML document that does not 
inherit the base URL or style information of the parent document.  If an 
INCLUDE element is truly desired, then it should be distinct from OBJECT, 
and it should simply include document fragments rather than necessarily 
complete documents.  However, server-side includes seem more efficient to

But then you have an extra trip to the server, and an extra download for 
the client.

If you find the disadvantages of SSI too great, there are alternatives 
like preprocessors.
