SuperScript to baseline offset

If I bring in RTF text that contains superscript (or subscript) information, the text attributes in that text range will contain the NSSuperscriptAttributeName attribute but apparently not the NSBaselineOffsetAttributeName.

At what point in the text layout process is NSSuperscriptAttributeName "changed" into a baseline offset?  If I want to change the way that the SuperScript is represented (say by substituting a smaller point size of the same font, or changing the magnitude of the baseline shift) where would I insert my code?
