I would still call *SAX* a read-only API because this class is not 
part of *SAX*. Possibly the class that is *not SAX* such as MSXML4 
would expose its own API which might be a read-write API. But none of 
this changes what SAX is and isn't.

I'm completely disagree with that. SAX is far from symmetric. It 
clearly intends that parser vendors will implement the XMLReader 
interface while parser clients will implement the ContentHandler 
interface. In practice, developers find ways to use both that were 
probably never intended. That's part of what makes programming fun, 
but it does not invalidate the clear record in the SAX documentation 
and various e-mail archives that SAX was always intended for client 
applications to read XML documents through a parser interface.
