This might be worth looking into.

Firefox used this for a type of bookmark folder in the past, I believe. Understanding why that feature was removed might be illuminating.

Hi @martinthomson . Thanks for sharing this!
Do you have any more info on this, or a link you can point us too?

I'd be doing whatever it is you would do with a search engine either way. Atom is an RFC though, FWIW.
