the current mechanism for serializing the internal ReqIf model to XML makes use of an intermediate model to model transformation. Even though this transformation is very fast, it has some disadvantages:
* errors that might occur during deserialization need to be traced during the model to model transformation (this is not yet implemented and leads to unspecific error messages)
* during load and safe the complete model is transformed into a second model. This model is more complex than the original ReqIf meta model and thus additionally consumes at least the same amount of memory as the original model.
* During development the developer might accidentally choose the wrong resource or factory.
* the intermediate model to model transformation is very generic and works well for models that comply 100% to the ReqIf standard. However, in case of errors in the input model it is hard to identify the original source of an error during transformation. 

I do not expect too much effort for implementing a resource that is based on the ecore XMLResourceImpl and directly loads and safes the data without any intermediate transformation.
