If I have an exercise group in a division exercises, I can give it an xml:id, and reference it.
Let's say the exercisegroup contains problems 4-11.
If I make an xref to this exercisegroup, the text of the xref will be "Exercise Group 4 - 11".
Although the exercisegroup is titled "Exercise Group." I find the xref text to be a bit unnatural. I think it sounds better to me if this reads simply "Exercises 4 - 11".
I know I can add xml:ids to the first and last problem in the group, and do my xref as
<xref first="first" last="last" text="local">Exercises</xref> but it seems more natural to me to simply xref the group.
It's fine if others prefer the text "Exercise Group" but I was curious whether I was the only one who thought that "Exercises" sounded a bit better.
