Another source of interest is 
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3092.pdf  esp. 
section 7.6.
This is the FCD, so we can expect this getting standardized with some 
minor changes only.

I don't know of examples. The FCD states that the behavior of attributes 
other than the predefined ones are implementation defined. That is you 
can define your own attributes at will in the compiler implementation.  
(hmm - that would prevent the standardization of other attributes in the 
future. I'm going to raise that issue in csc++...)
