No, there are several space efficient ways to combine several DocTypes. 
The most general is probably to define some sort of EBMLChangeDocType 
element. You could end up with elements that means different things in 
different contexts, but that is really not much of a problem. Normally 
when you combine XML languages you don't want to really mix them, just 
use one within the other. I am confident that both EBML and the DTD 
format can be extended in the future to allow for this.

I think that the last instance of an element is what is referenced.

You mean this:

Looks to me like your mail server (62.62.156.28) is blocked by RBL
