Say one source term has different translations according to a given context and that given context is described in a comment in the source term entry. Is it possible to set Xbench to take this comment into account when flagging term errors so as to avoid false positives?
Xbench does not have this functionality. If the format is MultiTerm, you have the resource of placing all possible targets under the same term, as opposed to creating separate terms.
Currently there is no plan to parse user comments in glossaries with AI to try to infer user intent or context.
