I think both views are consistent with MS ... messy ... 'technical' ... 

XT is streaming in a sense that XSLProcessorImpl is actually 
SAXParser  ;-) 


import org.xml.sax.Parser;
public interface XSLProcessor extends Parser {

public class XSLProcessorImpl implements XSLProcessor, Cloneable, ParameterSet {


Does it mean XT is  'streaming' ?  Yes. SAXParser  is 'streaming' 
by definition. 

Has it memory footprint? Yes, because this 'SAXParser'  is very 
special, it loads the entire document into memory.

Is MS talking about *this* memory footprint or about some other memory 
footprint ?

No way to answer.  

We can only guess what do they mean, because having XSLT engine in form of 
SAXParser already saves some memory. Not "that much", but ...


PS. Streaming XSLT is doable, but it is hardly 'one man project'. 
It is 2-man-year project. But  weekends are too short.
