Some people (such as [[Erwin Schrödinger]]{{citation neededdate=October 2015}}) have objected to this derivation on the grounds that [[pseudotensor]]s are inappropriate objects in general relativity, but the conservation law only requires the use of the 4[[divergence]] of a pseudotensor which is, in this case, a tensor (which also vanishes). Also, most pseudotensors are sections of [[jet bundle]]s, which are now recognized as perfectly valid objects in GR.
