How would you suggest that I mark verses that cover a range of canonical
verses?  Options I can think of:

A) <verseStart MID="Ps.2.1-2"/>...<verseEnd MIDREF="Ps.2.1-2"/>

B) <verseStart MID="Ps.2.1"/><verseStart MID="Ps.2.2"/>...<verseEnd
MIDREF="Ps.2.1"/><verseEnd MIDREF="Ps.2.2"/>

C) <verseStart MID="Ps.2.1"/><verseStart MID="Ps.2.2"/>...<verseEnd
MIDREF="Ps.2.2"/><verseEnd MIDREF="Ps.2.1"/>

D) <verseStart MID="Ps.2.1 Ps.2.2"/>...<verseEnd MIDREF="Ps.2.1
Ps.2.2"/> (I'm sure that's invalid, but you get my point.)

A is simplest from the encoding standpoint.  B, C, & D are more
difficult to encode, but easier to decode when crossing a chapter
boundary (luckily that is very uncommon).
