There are 2 issues

1. According to latest SAX doc from http://www.saxproject.org/, when external-general-entities should be always true when validating. In the test case, I successfully set to false after I set validating to true.

2. This one I am not quite sure. From the original doc, http://www.megginson.com/SAX/Java/features.html, it has a access field specify that external-general-entities and external-parameter-entites are read-only when parsing. In the latest doc from saxproject.org, it doesn't have access field. So I am not sure whether I can set it at all (ie. when I try to setFeature(external-general-entities), it should throw SAXNotSupportedException)
