In the data files that I've looked at there seem to be a few cases where glottalized w and glottalized y have a raised comma written directly above them. This is not a standard representation in either IPA or in the Americanist forms used traditionally for writing Moses. So I would definitely change any w or y that has a raised comma above it into either w/y followed by raised comma or w/y followed by superscript glottal (depending on which we finally decide to do). I don't know why there are these w/y with raised comma above them since in the lexware database that is not how those sounds were represented.
