I traced this through to SDOXMLWriter::writeDO, line 1105 in my version
if (dataObjectType.isSequencedType())
{
SequencePtr sequence = dataObject->getSequence();
if (sequence)
{
for (i=0; i<sequence->size(); i++)
{
if (sequence->isText(i))
{
// do unstructured text stuff, and
continue;
} // end TextType
const Property& seqProp = sequence->getProperty(i);
SDOXMLString seqPropName = seqProp.getName();
const Type& seqPropType = seqProp.getType();
if (seqPropType.isDataObjectType())
{
// do DataObject stuff
} // end DataObject
else
{
// Sequence member is a primitive
writeXMLElement(writer,
seqPropName,
sequence->getCStringValue(i));
} // end DataType
} // end - iterate over sequence
}
} // end sequence handling
so it seems that if the data object is sequenced, it will write primitive
properties as elements unconditionally. The code to handle non-sequenced
objects, which follows this snippet, has some much more complicated
conditions.Looks like it has been updated while the sequenced clause has
been allowed to go a bit stale.

Caroline Maynard commented on TUSCANY-963:
------------------------------------------
It's not necessary for the element to be open for this to occur, it's
sufficient for it to be sequenced.
