In the Java implementation we do the following:
1. If a sequenced type is created programatically, we map all the
properties to XML elements - so any property can be added to the sequence.
That sounds right.
2. If a sequenced XSD-based type, then only properties that map to
elements can be added to the sequence. Trying to add an attribute property
will throw an exception. XSDHelper.isAttribute() is the way that the user
can determine whether or not a property can be added to the sequence.

OK.. that was my initial proposal.
Can you confirm that for a sequenced DataObject if I set a property using
e.g. setString("prop", "text") then that setting will added to the sequence
as if getSequence().add("prop", "text") was used?
