Such analyses relied rather heavily on delicate manipulations of the fields of non-commuting coordinates whose charges were under study. Here we derive the same charges in a "coordinate-independent" symplectic-geometry type of approach and find results that are consistent with the ones of hep-th/0607221.12 pages, RevTex4; clarifying remarks added and incorrect statement rectified; typos correctedHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
