My attempts here are to mimic the `pagination()` method shared by actions. I'm tentatively adding the `$count` property to actions so that we can query the number of notices ''being displayed'' per page prior to calling the actual `pagination()` method itself, since document relationship `<link>` elements need to be output inside of `showHead()`, before `showContent()`, which is where `pagination()` is, gets called.
