Re: [xsl] XSLT 2.1 streaming: only benefits memory?

Please see

"Streaming achieves two important objectives: it allows large documents 
to be transformed without requiring correspondingly large amounts of 
memory; and it allows the processor to start producing output before it 
has finished receiving its input, thus reducing latency."

For example, a series of deposits and withdrawals to a bank account over a period of time is a stream. A stream-based program would be long running and would process the deposits and withdrawals as they occur. Notice in this example, the key issue is incremental processing of data as the data arrives; the key issue is not one of memory (in fact, memory isn't even an issue).
