• The website URL just got overhauled and I made changes here. But I think this is an unreliable way to figure out where something is really hosted? Maybe better to use the "base-url" from the publisher file (if set)?
• The "visible-id" template is probably right, but the "containing-filename" template is where it really comes from.

So, simply suggesting this could be improved, if it is important. If it is not that important, maybe a code comment to that effect is in order so nobody else gets too excited.
