In process of my pursuit of that problem I address elsewhere, I've been trying some experiments with conditional bootstraps, but I've run into a problem that I'm getting error messages seeming to suggest I'm using the wrong groups or tags (at least it complained about one of the group.tag syntax things I did); is there any way to actually find out what a given group and tag for something is for sure? As an example, I'm trying to do a check in the condition to see if any one of the three languages is present (since otherwise the bootstrap shouldn't activate) so I needed to know what the group.tag for each language was. How could I find this out except by guesswork?
