Hi Caroline,

The last fix checked in addresses a derivation by restriction issue. Checkout the latest source and build it and use that jar.
I tested using the latest jar and do not get the error (I got the error using an earlier jar)
This is the test program.

public class XmlBeansTest {
    public static void main(String[] args) {
        String schema = "<xs:schema xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" elementFormDefault=\"qualified\" attributeFormDefault=\"unqualified\">\n" +
                "    <xs:element name=\"RootElement\">\n" +
                "        <xs:annotation>\n" +
                "            <xs:documentation>Comment describing your root element</xs:documentation>\n" +
                "        </xs:annotation>\n" +
                "        <xs:complexType>\n" +
                "            <xs:sequence>\n" +
                "                <xs:element ref=\"Child\"/>\n" +
                "                <xs:element ref=\"ChildExtended\"/>\n" +
                "                <xs:element ref=\"ChildRestricted\"/>\n" +
                "            </xs:sequence>\n" +
                "        </xs:complexType>\n" +
                "    </xs:element>\n" +
                "    <xs:element name=\"Child\" type=\"MixedType\"/>\n" +
                "    <xs:element name=\"ChildRestricted\" type=\"MixedTypeRestricted\"/>\n" +
                "    <xs:element name=\"ChildExtended\" type=\"MixedTypeExtended\"/>\n" +
                "    <xs:complexType name=\"MixedType\" mixed=\"true\"/>\n" +
                "    <xs:complexType name=\"MixedTypeExtended\" mixed=\"true\">\n" +
                "        <xs:complexContent mixed=\"true\">\n" +
                "            <xs:extension base=\"MixedType\"/>\n" +
                "        </xs:complexContent>\n" +
                "    </xs:complexType>\n" +
                "    <xs:complexType name=\"MixedTypeRestricted\" mixed=\"true\">\n" +
                "        <xs:complexContent mixed=\"true\">\n" +
                "            <xs:restriction base=\"MixedType\"/>\n" +
                "        </xs:complexContent>\n" +
                "    </xs:complexType>\n" +
                "</xs:schema>";
        String testxml = "<RootElement xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">\n" +
                "    <Child>text</Child> \n" +
                "    <ChildExtended>text1</ChildExtended>\n" +
                "    <ChildRestricted>text2</ChildRestricted>\n" +
                "</RootElement>";
        try {
            SchemaTypeSystem sts1 = XmlBeans.compileXsd(new XmlObject[]{XmlObject.Factory.parse(schema)},
                    XmlBeans.getBuiltinTypeSystem(), null);
            XmlObject x1 = sts1.parse(testxml, sts1.findDocumentType(new QName("", "RootElement")), null);
            XmlOptions xo = new XmlOptions();
            ArrayList<XmlValidationError> errorlist = new ArrayList<XmlValidationError>();
            xo.setErrorListener(errorlist);
            if (!x1.validate(xo)) {
                for (XmlValidationError e : errorlist) {
                    System.out.println(e.getMessage());
                }
            }
        } catch (XmlException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }

    }
}

Jerry

          Components: Validator
    Affects Versions: Version 2.4

I have noticed that when an element is defined as a restriction from a mixed type, if there is some text in this element the Xmlbeans validation fails.However the same xml file is valid if I run it against schema validation in XmlSpy. Here is the example (I tried to make it as simple as possible):

xml schema:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:element name="RootElement">
        <xs:annotation>
            <xs:documentation>Comment describing your root element</xs:documentation>
        </xs:annotation>
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="Child"/>
                <xs:element ref="ChildExtended"/>
                <xs:element ref="ChildRestricted"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:element name="Child" type="MixedType"/>
    <xs:element name="ChildRestricted" type="MixedTypeRestricted"/>
    <xs:element name="ChildExtended" type="MixedTypeExtended"/>
    <xs:complexType name="MixedType" mixed="true"/>
    <xs:complexType name="MixedTypeExtended" mixed="true">
        <xs:complexContent mixed="true">
            <xs:extension base="MixedType"/>
        </xs:complexContent>
    </xs:complexType>
    <xs:complexType name="MixedTypeRestricted" mixed="true">
        <xs:complexContent mixed="true">
            <xs:restriction base="MixedType"/>
        </xs:complexContent>
    </xs:complexType>
</xs:schema>

xml file:
<RootElement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <Child>text</Child> 
    <ChildExtended>text1</ChildExtended>
    <ChildRestricted>text2</ChildRestricted>
</RootElement>

For XmlSpy, this is valid. Here's what I get when validating with Xmlbeans :

Message: Element 'ChildRestricted' with empty content type cannot have text or element content.
Location of invalid XML: <xml-fragment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>

I guess this is linked to this issue :
