HTML 5: <include> tag?

As I was working on my website to include a common footer across all the 
pages on an Apache webserver, I discovered that it could perhaps be done 
more elegantly by adding an <include/> tag to the HTML specification. Such 
a tag, if the HTML DOM is modified to add it, could supercede the 
<object/> tag and serve as a single interface for the browser to parse its 
content file name by extension type to render the appropriate file on the 
page. It will absorb into it the current SSI functionality offered in a 
variety of forms by various intermediate web server features.

Including this in the HTML specification itself has the advantage of 
applying ACL rules to an HTML page without being subjected to the 
web-server specific file security requirements, while applying the website 
ACL requirements by page or link, thus not having to worry about any 
security breaches (assuming that all the current SSIs serve up the 
included file content and not the SSI instruction itself when the page 
source is displayed by the browser so as not to reveal the file name and 
location of the included file).
