The 4.4 "XML Processor Treatment of Entities and References" of
XML 1.0 SE spec says that the ParameterEntity may be used in the
Entity Value and will be resolved as 'Included in literal' (see table).

But the parser failed to parse parameter entity in entity value
(both crimson in JDK 1.4.1 and xerces in JAXP 1.2 build b18).

See the log below for details:

% cat xml_ex.xml
<?xml version="1.0" ?>
<!DOCTYPE root [
  <!ELEMENT root ANY>
  <!ENTITY % text 'internal'>
  <!ENTITY inEntity '%text;' >
]>
<root>data</root>

% cat xml_ex.java
import java.io.PrintStream;
import java.io.File;
import javax.xml.parsers.SAXParserFactory;
import javax.xml.parsers.SAXParser;
import org.xml.sax.helpers.DefaultHandler;

public class xml_ex {

    public static void main(String [] args) {
        try {
            SAXParserFactory spf = SAXParserFactory.newInstance();
            spf.setNamespaceAware(true);
            spf.setValidating(true);
            SAXParser parser = spf.newSAXParser();
            File xmlFile = new File(args[0]);
            parser.parse(xmlFile, new DefaultHandler());
            System.out.println("Passed.");
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("Failed.");
        }
    }
}
