Hi TeXmacs folks,

I'm trying to get more sophisticated and say-what-I-mean in my use of 
TeXmacs, but am having trouble figuring out how to introduce an 
automatic counter that resets at each chapter.  I'm trying to follow the 
descriptions in 
http://www.texmacs.org/tmdoc/main/styles/std/std-counter-dtd.en.html, 
but somehow I think I'm missing something.  I have attached an example 
TeXmacs file that illustrates my woes.  My apologies if this is obvious 
from the documentation, but somehow I'm not getting it; I'm not sure 
whether my basic use of counters is misguided but looks like it's 
working (and thus is confusing me), or whether instead I am using basic 
counters correctly but have blown it when it comes to counter groups.

Thanks for any help
you can provide,
     Dave W
