Result as Xml, and lower/upper case

[dooverone]

Hi,
According to the documentation it is possible to name xml nodes with mix of 
upper/lower case, i.e
<person>
  <lastName>Johnson</lastName>
</person>

But it doesn't work for me. All nodes are lower case:

  <select id="getAffairForXmlDocumentByKey" resultClass="xml" 
parameterClass="string" xmlResultName="person">
    SELECT   AFFR.AFFAIR_NO AS affairNumber
                 ,DEBT.LASTNAME as lastName
    FROM AFFAIRS AFFR
    LEFT JOIN DEBTORS DEBT ON (DEBT.DEBT_ID = AFFR.DEBT_DEBT_ID)
...
</select>

But I got xml like this
<person>
  <affairnumber>2342342</affairnumber>
  <lastname>Johnson</lastname>
</person>

Ibatis 2.1.0

Postgresql 8.0.1

Any help would be appreciated.
Anyone tried this ?

Cheers
