How do I get the attribute of an equation, that returns the feasibility status of an equation?

Is there any equation attribute, that gives back the feasibility status of an equation?

Equation attribute .infeas provides the amount by which an equation is infeasible falling below its lower bound or above its upper bound. This is defined as max(0, lower bound - level, level - upper bound).

Usage of this model attribute is for example illustrated in the model feasopt1 in the GAMS model library.
