Thank you both for the replies. In fact your little extra piece of 
explanation wouldn't go amiss in the documentation.

More generally, when one is trying to use a package for the first time, 
it can be difficult transforming the rather abstract presentation in the 
documentation into concrete use. E.g., I have been aware of xtemplate 
for some time but only recently, having "discovered" the acro package of 
Clemens Niederberger and seeing the clear presentation of an actual use 
of xtemplate, does the documentation "make sense". It would be helpful 
if the reader of the documentation could be pointed toward paradigmatic 
examples of use of packages or modules. (If not in the package 
documentation then perhaps in the l3StyleGuide?)

(In fact acro.sty is the most elegantly and clearly presented .sty file 
I've met. Unfortunately it isn't picked out by the MiKTeX filter with 
any likely keyword for someone looking for expl3 or xtemplate examples.)
