Frances Karttunen: 

-IXTLAN compound postposition before, in the presence of / delante, delante de los ojos de alguno, en su presencia (C) [(4)Cf.21r,21v, (4)Tp.137,167]. This is synonymous with –ĪXTLAH, also attested in C. T is ambiguous between the two, since it loses booth N and H word-finally Where additional suffixes are added to form the honorific, T has the form with N, -ĪXTLANTZINCO. See ĪX-TLI, -TLAN.
