That example is non normative and is about a section explaining the  
differences between CDI and CDR. The document itself is about CDR as  
should be clear from the title from section 2. However, I can see that it  
could cause some confusion.

Ah, that explains it.

I think DOM Level 3 Core (and earlier iterations) already covers documents  
using multiple namespaces from a DOM point of view.

This is really a CSS issue like I said before. CSS defines the rules for  
determining the height and width of a replaced element.
