I'd like to hear as many opinions on this point as possible.  What is
the rationale for *not* deriving SAXException from IOException when
(for example) java.net.MalformedURLException and
java.util.zip.ZipException are derived from IOException?

I especially like the idea that higher-level libraries could have

  void importXML (String uri) throws IOException;

without the application's having any direct dependency on SAX
interfaces.  It could accomplish the same thing by having a
SAXExceptionAdapter that embeds the SAXException and extends
IOException, but that seems like a lot of unnecessary fuss for a very
common case.

Opinions?


All the best,


David
