FWIW, we think of this kind of implicit/explicit pair as almost
the defining examples of head and trailer, and their correspondence
as the defining example of the correspondence between head
and trailer. The only cases that escape being tagged as head and
trailer are those (not uncommon) in which the two functions are
combined, i.e. those that fall between the end of one div and the
beginning of the next and serve both as trailer to the one and
head to the other, 'Hic explicit liber tertius implicitque liber
quartus.'  Those sometimes end up rudely hacked apart into
trailer and head, but more often tagged as one or the other.

As for closer/opener, though we usually honor its grouping function,
we also choose it (for want of something better) not only for
mixed content in which <signed, etc. appear, but also as a 
catch-all for formulaic opening and closing phrases that do not fall 
happily into head/trailer, dateline, epigraph, byline, or argument, e.g.

<opener>To the tune of Michigan Madness</opener>
<closer>Soli deo gloria.</closer>

But that is purely local practice. The first *could* be regarded
as a kind of <head>, the second as a mere <seg>, and the last
as (???) an <epigraph>. I'd be interested to hear how others
tag these things.
