[xsl] XSLT 2.1 streaming: only benefits memory?

2010-08-14 06:51:33
Hi Folks,

In what I've read, the main benefit of the streaming capability in XSLT 2.1 is 
memory. Namely, an XSLT processor won't have to hold in memory a representation 
of the entire XML document. 

From the reading that I have done on streaming in general (i.e., not 
XSLT-specific), I get the impression that the main benefit of streaming is 
that it enables processing before the complete set of data is available. 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).


QUESTION

Is the streaming capability in XSLT 2.1 just for dealing with large XML 
documents or will it support data that arrives in bits and pieces (i.e., 
streamed data)?
