OK.

    dS(0, {"representation": "tensor"}) \
  + dS(0, {"representation": "tensor"})

works, but

    dS({"representation": "tensor"}) \
  + dS({"representation": "tensor"})

doesn't. Seems like a bug.

Turns out I can't use this anyway because facet normals are not 
supported by FFC with the tensor representation,

    ffc.tensor.monomialextraction.MonomialException: No handler defined 
for terminal FacetNormal
