xsi:type attribute not set correctly

[David Kocher]

Dear all,
        We have a derived type from short in our schema such as:
    <xs:simpleType name="MyDerivedFromShortType">
        <xs:restriction base="xs:short">
            <xs:minInclusive value="1"/>
            <xs:maxInclusive value="100"/>
        </xs:restriction>
    </xs:simpleType>
When sending an instance document (using document/literal) over the wire 
 with axis (1.2), it is serialized as:

        <ns2:MyDerivedFromShort xsi:type="xsd:short">99</ns2:MyDerivedFromShort>
However, I this seems to be incorrect, as MyDerivedFromShort is derived 
(!) from xs:short but not xs:short itself.

When parsing this with Xerces it will throw
Validation error: LineNumber: 48 ColumnNumber: 2883 Message: 
cvc-elt.4.3: Type 'xsd:short' is not validly derived from the type 
definition, 'MyDerivedFromShortType', of element 'ns2:MyDerivedFromShort'.:

I just upgraded to 1.2 final; as far as I can tell this bug was not 
present in the latest release candidate.

Please let me know if I missed something or if there is any known 
workaround.

Thanks!
