I have to admit, I never heard of that stuff before. And I actually do not  
know what exactly you want to ask?
Just downloaded the example data-set from this page:  
http://www.lvermgeo.rlp.de/index.php?id=2837

http://www.lvermgeo.rlp.de/index.php?id=2837&no_cache=1&cid=31&did=8405&sechash=93dd2e

which is a zipped xml file of 3,5 MB. Extracted, it's about 128 MB.
Loading  ( choose to view all file formats in the vector loading dialog)  
all 94 layers and tables at once in QGIS 2.2 took some minutes, so  
digestion of this format seems not to be very performant.
Having loaded only 2 layers, it is much faster, but moving the map content  
takes a while to render, even on my new and super fast machine.

So, possible usage in QGIS as far as I could elaborate:
- Viewing layers and tables
- Editing is not possible
- Saving layers in other formats works (e.g as shp, and after building a  
spatial index it's rendering much faster)

What else do you need to do with that?

Cheers
Bernd
