I believe Daniela's point is that people shouldn't come up with 
home-brewed XML processing engines nowadays just as nobody's writing 
home-brewed database engines anymore. XML processing shouldn't be a 
matter of art, while it shouldn't perform poorly by default neither.

Imagine a guy who only wants to rename some elements in an XML document. 
SAX filter/custom XmlReader is one way to go, 10-lines XSLT stylesheet 
is another one (and a better one as being declarative).
The sad thing is that XSLT impementations currently aren't smart enough 
to realize that such XML transformation can be done in a streaming way, 
so XSLT way's perf will be definitely worse and XSLT will definitely be 
the one to blame.
