Err ... that's the behaviour of the DefaultHandler if supplied to an 
XMLReader via setEntityResolver. What behaviour does the spec require 
if I do this,

  XMLReader reader = XMLReaderFactory.createXMLReader();
  reader.setContentHandler(myHandler);
  reader.parse(someInputSource);

Unless I'm missing something, the spec is completely silent on entity 
resolution policy in this (surely very common) case. Like I said, it's 
_probably_ true that _most_ implementations will use the same policy as 
the DefaultHandler, but that doesn't appear to be required by the spec. 
All it says is,

  If the application does not register an entity resolver, the XMLReader
  will perform its own default resolution.

in the javadoc for setEntityResolver without say what that default is.

Yup.
