Constraints that ensure a correct physical interpretation of the corresponding particle states are presented. Dirac-like equations based on both multiplicity-free and generic infinite-component $\bar{SL}(3,R)$ representations are outlined.4 pages, TeX; Talk given at the XI Yugoslav Symposium on Nuclear and Particle Physics, Studenica, September 1998General Relativity and Quantum Cosmologytext
