Mattias, the usage of xsi:type is solely because object hierarchies are being used in the AOM. Using xsi:type allows serializers to know the type they are getting before having to parse it in.. however, even without xsi:type, your serialization would still not be correct for the xsd given (i.e. let us pretend there is only a C_ATTRIBUTE, with no subclasses). Any reference to an element of type C_ATTRIBUTE in xml should result in an xml entry named by the 'element with type C_ATTRIBUTE' i.e. 'children'. You never put type names into the actual xml instances, merely element names. And for sequences, this means repeating the xml entry name 'children' (augmented in this case by an xsi:type to help with the subclasses).
