Problems with namespace prefixes in version 2

I am using XmlBeans v2 to access appinfo elements in a schema, which
I then process to create XML based on that schema.  A portion of the
schema is:

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:ontology="http://www.aptas.com/ontology"
    xmlns:papyrus="http://www.aptas.com/papyrus"
    targetNamespace="http://www.aptas.com/ontology"
    elementFormDefault="unqualified"
    attributeFormDefault="unqualified">
    <xs:import namespace="http://www.aptas.com/papyrus"
        schemaLocation="xsd/PapyrusAppinfo.xsd" />
    <xs:complexType name="ontology">
        ...omitted for brevity
    </xs:complexType>
    <xs:element name="datafeed">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="ontology" type="ontology:ontology">
                </xs:element>
            </xs:sequence>
            <xs:attribute name="locale" type="xs:language"
                default="en">
            </xs:attribute>
        </xs:complexType>
    </xs:element>
</xs:schema>

A sample of the generated XML is:

<?xml version="1.0" encoding="UTF-8"?>
<datafeed xmlns="http://www.aptas.com/ontology" locale="en-US">
    <ontology>
      ...stuff omitted
    </ontology>
</datafeed>

The problem is, this XML does not validate against the schema.  The
only way I can get it to validate is to define the namespace prefix
"ontology" in the XML, then prefix the datafeed element, and only the
datafeed element, with "ontology:".

The first question, non-XmlBeans-related, is why the datafeed element
needs to be prefixed?  I am hoping a schema guru can educate me.

The second question is, I can't find the prefix to add.  When I get
the SchemaTypeSystem from the XmlBeans compiler, the SchemaType and
the SchemaLocalElement for the datafeed element both have a QName
with a correct namespaceURI and localPart, but the prefix is an empty
string.  Assuming I really need it, where can I find the prefix?

Thank you.  If I have not provided enough information, please let me
know and I will send more.
