The vyconf analogue of cli-shell-api getCompletionEnv (where completion here refers to bash completion) was added in T8061. The greater part of the information provided under tab completion is drawn from the reference tree data of the XML elements help and valueHelp, and from the structure of the proposed config, as implemented in T8061. The one remaining piece of information needed is the translation of the reference tree data of the XML element completionHelp (where completion here refers to hints of allowable values of a tag node or leaf node, when not already provided by the information above).
