Where did you get that impression? (I ask so I can make it clearer).
The intention of the <ext> is that you can put whatever you want in
there. You just give it a name.
.... whatever you like, could be hex data for all I care.
Using the domain name prefix is a good idea to prevent namespace
Readers which don't support your extension simply ignore it. Editors
(i.e. which write XODE files), should in a perfect world store your
extension data, and keep it attached to its node to be written out
verbatim on saving.

I think it already does what you want.

These should be specified in <world>. They will be for the next
version. This is a gap in the spec.
