validation errors

                 Key: XERCESC-1633
                 URL: http://issues.apache.org/jira/browse/XERCESC-1633
             Project: Xerces-C++
          Issue Type: Bug
          Components: Validating Parser (Schema) (Xerces 1.5 or up only)
    Affects Versions: 2.6.0
         Environment: Testing on Windows XP
            Reporter: Jennifer Rapp
            Priority: Critical


I am trying to test parsing using 'list' or 'union' for finalDefault and I'm 
getting parsing errors from the validation parser for a valid schema:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
    xmlns:xs="http://www.w3.org/2001/XMLSchema";
    targetNamespace="http://www.quovadx.com/schema_test";
    xmlns:st="http://www.quovadx.com/schema_test";
    finalDefault="list union"
    >
    <xs:element name="root">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="gst0" 
type="st:gst_explicit_none"></xs:element>
                <xs:element name="gst1" type="st:gst_none"></xs:element>
                <xs:element name="gst2" type="st:gst_r"></xs:element>
                <xs:element name="gst3" type="st:gst_u"></xs:element>
                <xs:element name="gst4" type="st:gst_rl"></xs:element>
                <xs:element name="gst5" type="st:gst_ru"></xs:element>
                <xs:element name="gst6" type="st:gst_lu"></xs:element>
                <xs:element name="gst7" type="st:gst_rlu"></xs:element>
                <xs:element name="gst8" type="st:gst_all"></xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    
    <xs:simpleType name="gst_explicit_none" final=""><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_none"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_r" final="restriction"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_l" final="list"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_u" final="union"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_rl" final="restriction list"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_ru" final="restriction union"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_lu" final="list union"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_rlu" final="restriction list union"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
    <xs:simpleType name="gst_all" final="#all"><xs:union 
memberTypes="xs:int"></xs:union></xs:simpleType>
</xs:schema>

And the following xml instance

<?xml version="1.0" encoding="UTF-8"?>
<st:root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
 xsi:schemaLocation="http://www.quovadx.com/schema_test schema_test.xsd"
 xmlns:st="http://www.quovadx.com/schema_test";>
    <gst0>1</gst0>
    <gst1>2</gst1>
    <gst2>3</gst2>
    <gst3>4</gst3>
    <gst4>5</gst4>
    <gst5>6</gst5>
    <gst6>7</gst6>
    <gst7>8</gst7>
    <gst8>9</gst8>
</st:root>

Produces the following errors running PParse:

Error at file C:\CurrentProject\5.5\AR\10237\Xerces_bug\schema_test.xsd, line 7,
 char 6
  Message: Invalid final value: list union

Error at file C:\CurrentProject\5.5\AR\10237\Xerces_bug\schema_test.xsd, line 7,
 char 6
  Message: Invalid final value: list union

I believe the issue is with the validation.  Currently 'list' and 'schema' are 
only allowed for simpleType definitions, but should be allowed in the schema's 
finalDefault attribute as well.
