Not using the serialization framework. The serializer framework exists
to serialize database objects; extra attributes on the object are not
in the database, and so are not serialized.
An alternative approach is to use the SimpleJSON library directly. Set
up a python dictionary that contains the data structure you want to
serialize (or write a proxy object that behaves like a dictionary),
and pass it to the SimpleJSON library. A similar approach will work
for XML.

If you pass a fields=(...) option to the serializer, only the fields
named will be serialized. e.g.:
txt = serializers.serialize('json', data, fields=('attr1','attr2'))
