[osis-core] Parallel passage with multiple references.

[Todd Tillinghast]

At the start of Matt.3 (CEV) after the section title 
"The Preaching of John the Baptist" there is a parallel passage
reference (Mark 1.1-8; Luke 3.1-18; John 1.19-28).

Initially I was planning on having the <reference> for the parallel
passage as a direct child of the <div type="x-section">.  But when there
are multiple parallel passage references it would seem better to enclose
them in some element.  The best element for the job would seem to be
<seg> as follows:

<div type="x-section" osisRef="Matt.3.1-Matt.3.12">
	<title type="section">The Preaching of John the Baptist</title>
	<seg type="parallelPassage">(<reference
osisRef="Mark.1.1-Mark.1.8" type="parallelPassage">Mark
1.1-8</reference>; <reference osisRef="Luke.3.1-Luke.3.18"
type="parallelPassage">Luke 3.1-18</reference>; <reference
osisRef="John.1.19-John.1.28" type="parallelPassage">John
1.19-28</reference>)</seg>
	<p>...</p> 
</div>

The alternative would be as follows:
<div type="x-section" osisRef="Matt.3.1-Matt.3.12">
	<title type="section">The Preaching of John the Baptist</title>
	<reference osisRef="Mark.1.1-Mark.1.8"
type="parallelPassage">Mark 1.1-8</reference>
	<reference osisRef="Luke.3.1-Luke.3.18"
type="parallelPassage">Luke 3.1-18</reference>
	<reference osisRef="John.1.19-John.1.28"
type="parallelPassage">John 1.19-28</reference>
	<p>...</p> 
</div> 

At present I am going to use the strategy in the first example above.

Any opinions as to which would be better?
