We report on a series of calculations for electron impact-excitation of the (5p^5)6p states in xenon from the ground state (5p^6)^1S_0. As in previous calculations for other noble-gas targets, we find strong evidence of channel coupling for all incident energies considered (between threshold and 200\,eV). Although qualitative agreement with the experimental results of Fons and Lin (Phys. Rev. A 58 (1998) 4603) is achieved, severe quantitative discrepancies of sometimes more than a factor of two remain.
