Sorry, I had in mind being able to re-apply event listeners to the DOM
once the new content was loaded. Of course you can do that in several
localised places rather than overall on the whole document (it will be
more efficient anyway). Still, it would be nice to be able to identify
that "all my bits of content are now loaded" and being able to have an
event handler that gets called once, rather than having to account for
all the IDs loading independently: I might want to do something that
involves several parts of the new content (e.g. highlight it to make
the change obvious to the user).
