We discussed a number of peculiarities of these languages and potential conceptual difficulties in the application of the UniMorph scheme to them and other languages.
we suggest the following extensions to the UniMorph schema: • human-readable labels for LGSPEC features, e.g., LGSPEC-TM instead of LGSPEC4 for Megrelian, 22 https://github.com/acoli-repo/unimorph • a ranking-based numerical scheme to represent iterative features in nominal inflection, • a ranking-based numerical scheme to encode multiple arguments of polyvalent verbs in head-marking languages, and • the postulation of a default ranking for verbal arguments, as well as the possibility to posit languagespecific rankings.
