You are right - it could be implemented in streaming fashion.
I think the trade off is
- streaming: slower than dom, less memory than dom, possibly more
complicated as you may need to store data for later.
- dom: quickest, more memory than streaming, simplest way to access citygml
data.

For now I lean toward dom as our input data is tiled to start with so I
don't expect really large files. I realize I have to revise the specs of
the problem:
I'll need to parse many medium size XML files.
