Abstract
A singularity on the light cone is conjectured which accounts for the Schwinger term required for the consistency of the Lee-Dashen-Gell-Mann sum rule with that of Cabibbo and Radicati. This singularity requires W3 to scale, rather than (as conventionally assumed) W3; because of positivity constraints, such behavior forbids in principle the usual scaling law for W1 and W2.
