Then we will keep up the name ;)

Unfortunately I do not know much about the XML stuff. But so far it seems to
be no problem to make a persistent DOM with ozone. But I'm confused about the
query languages. Can somebody clarify this a little bit? I've forwarded the
posting to Vincent.Aguilera also. Could his X-OQL be an option?

Yes, this is the way. But because of the central object activation of ozone it
could be a pretty overhead to access every Node object via RMI. So far I see
two ways to solve this problem: First is to cluster Node objects and second is
to put much of the code which accesses the DOM into the ozone server.
