Our motivation for this is that, for vector fields, the metric explicitly appears in each term and variation of it, gives the stress-energy tensor.
mu]v] is the stress-energy tensor for all the actions terms other that [[LAMBDA].
relied either on extra dimensions, or on an extension of the Riemannian theory with additional space-time curvatures introduced to yield the electromagnetic field characteristics, and where the stress-energy tensor regarded as provisional, will be eventually absent [2, 3, 4].
