In our application, we have what I call specialty documents that need to be created and retained. To simplify, we just have a table with a fkey to the document type and a memo field that stores the XML for the document data.

We also transfer information from one site to another by means of passing XML's of created records. So in this case we are creating an XML of a record which has a memo field containing an XML. Originally I was using the default OutPutFormat (1 elements) but when one tries to reverse the XML that contains an XML it bombs out. If I change the OutPutFormat to (3 raw) it works.

I do not have a good understanding on what and why the differences of the OutPutFormats for XML.

1- Elements      (default) Element-centric XML
2- Attributes     Attribute-centric XML
3- Raw            Generic, attribute-centric XML

Could anyone give me a better idea of how each of these should be used?

Thanks in advance.
