Surely the vector space of first Baire class is not exhausted by the cone of semicontinuous functions. More interestingly - still not by their differences. For an interesting class DBSC ("Differences of Bounded SemiContinuous") see: F. Chaatit and H.P. Rosenthal, arXiv:math/9901134. Boris Tsirelson (talk) 12:15, 30 January 2015 (CET)
