Object and New Insert Code Element

I've been trying for the longest time to insert code from an external 
file onto another page for a long time. Using <object> does not work to 
good. SSI is not supported and I even tried Flash.
I say one thing XHTML 2 desperately needs is a new element called 
insert. We would use it sort of like object except this would be for 
inserting code, (not images or applications!) from an external file 
source. This is something myself and many others NEED.

It would be so fun to be able to do this.

<insert data-"http://domain.com/directory/filename.ext" 
type-"application/xhtml+xml"/> or
<insert data-"http://domain.com/directory/filename.ext" 
type-"application/xhtml+xml">Your browser does not support XHTML 2.0. 
Sorry.</insert>
