Hmm, that might be a bug (I'll note that). You can probably partly fix 
it by doing like this:

	transformation = "$ALL_MESSAGES.filter(##tags exists and ##tags = 
$mainOutline.##tags)";

Note that this only works well when assigning a single tag to each 
message. I don't think there is a way to fix that. In theory this would 
work, but I haven't tried it:

	transformation = "$ALL_MESSAGES.filter(#flags.flag = 
$mainOutline.#flags.flag)";

(And if it works then I could improve `##tags` to work as well by 
defining a `tag` specifier similar to `flag`.)
