[Bioc-devel] problem with class definitions between S4Vectors and RNeXML in using Summarized Experiment

Completely agree on the importance of disambiguating class references
in the long term.

However I still think that just because we have a mechanism to
disambiguate means we shouldn't make an effort to avoid name clashes,
especially when the name clash is easy to avoid, like in the case
discussed here. Annotated is not a good name anyway. Something like
Annotatable would be more appropriate. Objects of this class **can**
be annotated but many of them are not.
