Where is that specified in the XML spec?

Anyway, there are differences betweem the three data models I mentioned, 
and any difference would be OK to illustrate that.

I don't understand. Currently, we're only talking about a RubyWay tree API.
An eventbased API is something else.
Or do you mean a tree API which doesn't require the whole tree to be in 
memory? I think in Python they have something like that; interesting.

That's why it might be a good fit as a base for a new API.
The new API would be based on a data model, defined as such; not on 
specifications of APIs that imply some data model.
