My proposal is to add 3 fields whose data would be the same as the cxxstd allowed values from Boost Build, using the first value of each choice ( currently 03, 11, 14, 17, 20 ).

standard = minimum C++ level for the library extended = same functionality in the library as the minimum C++ level but with extended use given higher C++ levels required = new functionality in the library above the minimum C++ level which requires given higher C++ levels

There's already a "std": [ "tr1"/"proposal" ] field, perhaps this should be extended rather than replaced? While undocumented, I note some libraries have already made use of this as std: [ "c++17" ] for example.
