Option to omit default fields in serialized lists and arrays #39
Description
When serializing a list with @ElementList or an array with @ElementArray, SimpleXML always seems to add an extra attribute, class for lists and length for arrays.
By using a custom TreeStrategy, I can change the attribute names but I cannot suppress the attributes altogether. (For @ElementList there is a hack by inlining the list and specifying @Path, but that is somewhat complicated and does not work for arrays.)
It would be great if there were an easy, standard way to suppress these attributes during serialization. Maybe with a separate field for the annotation (per element) or a new Strategy (which would take effect globally).
