So you tend to {1}, right?

Sorry, you totally lost me..(what is IMNSHO?)
A source by itself has nothing to do with XML or sax events. A source
can still implement the XMLizable interface for sax streaming. We have
the Cocoon SourceResolver which has a toSAX() method for a Source
object.
This method checks for the XMLizable interface. If the source implements
it, it's used. If not, the XMLizer component from excalibur is used
which does a mime-type to sax conversion and is therefore pluggable.
Is it that what you meant?
