Along the lines of the Core skills for a setting - For Savage Rifts, I've created a Setting (SetAdjust) component, and bootstrapped the Core Skills to the component.

    <thing id="setSRARifts" name="Savage Rifts" description="Setting for Savage Rifts\n\nSymbol &quot;Cr&quot; for credits\n\nCore Skills:\nAthletics\nCommon Knowledge\nNotice\nPersuasion\nStealth\n\nAdd to descriptions for Double Tap, Rapid Fire edges" compset="SetAdjust" uniqueness="unique">

One thing I'm not clear on, is if a Setting changes one or all of the Core Skills, what's the best way to handle that?
