Yes, that's correct. To run XPath you need a type-less model (DOM).

If you want to use XPath, then you will obviously incur some memory
overhead because of DOM. Without XPath, C++/Tree allows you to handle
very large documents with relatively small memory consumption using
the streaming mechanism (see the 'streaming' example).
