Consider the following references:

<reference osisRef="1Tim.3.8@s[They]"/>
<reference osisRef="1Tim.3.8@s[They]-1Tim.3.8@s[money.]"/>

Question 3: If you specify an osisRef with NO range AND a grain does

b) the contents within the brackets
c) the text stating at the first of the text in the brackets to the end
of the verse.
