I can't speak with any authority about Xalan, but my understanding is that it builds the tree concurrently with doing the transformation; by the time you've finished, you will normally have the complete tree in memory. This has benefits, but the memory you need still increases linearly with document size. I don't think so. You can process much larger inputs once incremental processing is enabled, and the style sheet fits, without running out of memory. Well, it still runs out of memory ultimately, but I don't think it's only streaming the result, significant parts of information associated with the input seems to be discarded too. The interesting challenge is to work out when you can discard parts of the tree that won't be needed again. I think this could be done quite easily for a small class of very simple stylesheets, but the general problem is quite hard.
