The Xerces-specific code that I used is:
SAXParser parser = new SAXParser(symbolTable, grammarPool);
parser.setEntityResolver(er);
parser.setErrorHandler(eh);
try {
parser.setFeature(Xerces2Constants.NAMESPACES_FEATURE_ID, true);
parser.setFeature(Xerces2Constants.VALIDATION_FEATURE_ID, true);
parser.setFeature(Xerces2Constants.SCHEMA_VALIDATION_FEATURE_ID, true);
parser.setFeature(Xerces2Constants.SCHEMA_FULL_CHECKING_FEATURE_ID, true);
// this will allow the parser not to emit DTD-related
// errors, as the jaxp spec demands
parser.setProperty(
"http://java.sun.com/xml/jaxp/properties/schemaLanguage";,
"http://www.w3.org/2001/XMLSchema";);
// This causes the external subset to be parsed.
parser.setFeature(
"http://xml.org/sax/features/external-general-entities ", true);
InputSource in = new InputSource(docReader);
in.setSystemId(docUri);
parser.parse(in);
...
The first comment is copied out of the Xerces implementation.

It works, I replied to Bob with the same advise about two months ago: http://marc.theaimsgroup.com/?l=xerces-j-dev&m=111156796913646&w=2

Well, we added support for this at users requests more that a year ago I think.

If you set isValidating to true on a SAXParserFactory, and set this property on the SAXParser instance, I believe you should get the behaviour you desire.

Schema has no concept of entities, so to do this you have to validate

again against the schema. I _think_ simply turning on both kinds of validation and having the proper doctype in the source file will do the right thing.
Nope. If you have a DOCTYPE with either an internal or external DTD, Xerces validates against the DTD.
Officially (officiously?), the folks who designed schemas expect us to
stop
using entities and migrate to some other variety of macro/external-data reference.
Not their problem, eh?
It's mine. A number of XML editors have started supporting this no concept, raising user expectations this is a valid combination.
