Saxon's <saxon:preview> element basically allows you to transform a sub-tree
as soon as it has been read, and then discard it from memory.

Not directly, but what you can do is write a SAX filter application that
sits between the XML parser and the XSLT processor, so that the filter
effectively breaks up the large document into lots of small ones and
transforms each small document as soon as it has been read.

I don't think that proposal is relevant (or it least, I haven't understood
its relevance!)
