> SDOUtil.loadDataGraph doesn't support scope, this improvement tries to address that.
> TypeHelper#define registers Types with the corresponding TypeHelper instance (scope)
> and XMLHelper#load utilizes the registered Types from the corresponding scope to instantiate DataObject instances.
> Unfortunately yet, current SDOUtil.loadDataGraph
> 2-1. can't designate scope to register serialized Types,
> 2-2. and can't designate scope to utilize already registered Types in order to instantiate user expected DataObject instances.
> An example of 2-1 is SerializeTypesTestCase had to
>         // The following is a kludge to force deserialization of metadata into a different TypeHelper (scope)
>         // TBD figure out a proper non-EMF way to do this.
>         Map options = new HashMap();
>         Object differentFromSerializing = ((TypeHelperImpl) deserializingTypeHelper).getExtendedMetaData();
>         options.put(XMLResource.OPTION_EXTENDED_META_DATA, differentFromSerializing);
> This proposal tries to adress scope by
> 2-1. add new SDOUtil.loadDataGraph(InputStream inputStream,Map options,TypeHelper scope)throws IOException
> 2-2. deprecate old SDOUtil.loadDataGraph(InputStream inputStream,Map options)throws IOException
> Any comment is welcomed.
