I apologize for the quick cut-n-paste and the opening tag should be <object>.

Anyway, the transformation is:
  1.  Look for elements in the source with the attribute "field" and use that as an element in the target. Hence, you see that

<String field="_str1" myId="28"><![CDATA[a test of referencing.]]></String>

becomes

<_str1><![CDATA[a test of string referencing.]]></_str1>

  2. If the element contains a reference instead, look for the data in the source instead of just using the reference. Hence, 

<String field="_str3" myIdRef="28"/>

becomes

<_str3><![CDATA[a test of string referencing.]]></_str3>

instead of

<_str3 myIdRef="28" />

I saw that one of the previous post actually address the problem pretty. Thanks to Jenni.

Cheers
