You are saying that any library which compiles in C++03 mode is not 
supported if uses Boost Test for its testing framework, otherwise it is 
still still supported.

Thanks for the CXXD support. If more people supported CXXD, and someone 
recommended it for review, and someone wanted to be the review manager, 
I certainly would like it be considered as a Boost library.

OTOH I think you can encourage feature addition for a particular library 
but I do not think forcing some C++11 on up construct or library to be 
used is something that Boost ought to be doing.
