Yes, <div>s should always be containers.  It's convenient when looking
for the context of a verse, etc. to be able to grab the smallest containing
<div>.  It's easier and more efficient to grab a <div> that is a container,
and the result is guaranteed to be well-formed XML unlike the text between
two milestones.

General comment on milestones and milestone-like usage of tags to denote
ranges of text: the section of the document thus delimited is no longer
well-formed XML, so it will be harder to process. (You can grab the smallest
div containing both milestones and make a pass through it, though.)
