I'm afraid I don't understand. Do you mean that with attribute which can 
specify that values of specific feature need to be checked when used inside 
condition? I can see that this attribute can be usefull, but on the other 
hand we currently only have <os> and <toolset> for which such handling was 
requested, and those features might well be handled by 'use-property' -- 
which we seem to need anyway.

I'm just trying to minimize the amount of new things to add ;-)
