But what exactly consitutes an XML Processor?  I would say that the SAX API
allows the application to intervene in several places that (according to the
XML 1.0 recommendation) are the responsibility of the XML processor.  So, in
this case, by deciding to pass the SAX Parser a character stream, the
application has taken on part of the responsibility of an XML processor -
namely the responsibility of dealing with any encoding issues, thereby
relieving the SAX processor of any need, indeed any right, to have an
opinion on how the encoding is performed.

Still not convinced?
