Query: A subtraction scheme for massive QED   We present an extension of the FKS subtraction scheme beyond next-to-leading
order to deal with soft singularities in fully differential calculations within
QED with massive fermions. After a detailed discussion of the
next-to-next-to-leading order case, we show how to extend the scheme to even
higher orders in perturbation theory. As an application we discuss the
computation of the next-to-next-to-leading order QED corrections to the muon
decay and present differential results with full electron mass dependence.
