Hi Jing -
examples from the Walmsley 2002 book are online, but the text is not. My print
copy (Ch 5, p91-92) says that schema-full-checking is the feature that checks
for non-deterministic content models, which is what bug 2054 revealed about
EML2.0.1   

See
http://www.datypic.com/books/defxmlschema/chapter05.html
Here's walmsley's example code:

Example 5-8. Java code to set schema validation in Xerces

SAXParser p=new SAXParser();
try {

// Turn schema validation on
p.setFeature
 ("http://xml.org/sax/features/validation", true);
p.setFeature
 ("http://apache.org/xml/features/validation/schema", true);
p.setFeature
 ("http://apache.org/xml/features/validation/schema-full-checking",
   true);
} catch (SAXException e) {
  System.out.println("error turning on validation");
}




whereas in eml/src/org/ecoinformatics/eml/SAXValidate.java it's like this:
...
   if (schemavalidate) {
        parser.setFeature(
            "http://apache.org/xml/features/validation/schema",
            true);
    }
...

which Walmsley says "allows most schema checking to take place"


BTW, googling for schema-full-checking xerces turned up this index on both the
xerces page and stylus studio (xmlSpy) so maybe that means that spy is using
xerces?
