That's an I/O error and the parser throws an IOException but does not 
call startDocument, fatalError, or endDocument.

The resource is malformed. The parser calls startDocument, 
fatalError, and endDocument.

This is also an I/O error and the parser throws an IOException and 
does not call startDocument, fatalError, or endDocument.
