I've submitted the SCA yesterday via Fax (sorry, forgot to mention).

I'm aware of that and I think you are totally right. My intention  
with the patch was more kind of "proof-of-concept" and idea  
brainstorming how the feature could be implemented - especially as I  
agree with you that a formal specification/discussion basis like a  
dedicated JSR would probably be overkill. This (the patch) seemed to  
me a "more" appropriate way of talking (or at least getting started  
talking) about the "same thing". Please just consider it as a  
prototype which has nothing to do with the final implementation nor  
it was intended to be targeted for  "submission and final  
integration" ( although I must admit that I am not familiar yet with  
the official submission process).

Best Regards,


PS: Thanks for getting more people involved
