We use the data-group syntax anywhere that we reference
data elements. We did this mostly so that we would
only have to define one mechanism for these data
references. Yes, that means that there are some components
of the syntax that don't add any value in some contexts, but
they don't hurt anything either. I won't claim this was the
best design choice, but it seems to be an OK design choice.
