The only difference is that an XMLResourceImpl's doSave will save (and
load) the extrinsic ID map, whereas a BinaryResourceImpl has no such map
to save (and will ignore it when you load a serialization that has
one). If you're using EMF 2.9 or later, have a look at the
org.eclipse.emf.ecore.resource.impl.BinaryResourceImpl.OPTION_STYLE_DATA_CONVERTER;
it can dramatically reduce the size of the serialization when you have
many long strings, and can be exploited to reduce the size of other data
types you might be serializing.
