If we allow Edm.Decimal to be used with IEEE decimal floating point, will we then support NaNn and +/-Infinity?

In other issues, e.g. ODATA-789, we have discussed extending the definition of Edm.Decimal to accomodate exponential form, to permit its use with IEEE decimal floating point values. This raises the issue of what to do with regard to the representation of NaN and +/- Infinity for floating point Edm.Decimal values in:
