I see. I have always understood the http://xml.org/sax/features/namespaces
feature to mean "behave as a vanilla XML 1.0 processor without reference to
the Namespaces in XML recommendation".
I think there are good reasons for treating the option in this way, rather
than just using it as a flag to control the parameters to startElement().
For one thing, the Namespaces recommendation introduces "namespace
constraints", (e.g. no ':' in entity name), which I would expect to be
flagged [1] by an XML processor in namespace mode but ignored when in plain
XML 1.0 mode.
