I have noticed that synonyms which are used only in the expansion of other 
synonyms will not be included in the list of synonyms if they themselves 
are used in the list of synonyms only. I don't really understand this 
sentence myself, so here is an example:

\abbreviation{CNS}{Crystallography \& \NMR\ System}
\abbreviation{NMR}{Nuclear Magnetic Resonance}
\starttext
	\CNS\ is an abbreviation % for \infull{CNS}
	\completelistofabbreviations
\stoptext

The list of abbreviations will only have one item (CNS). Removing the '%' 
character results in both items being listed.

Not surprisingly, I noticed this in two similar situations: with defined 
synonyms of another kind calling abbreviations not used elsewhere in the 
text, and with abbreviations used in the list of publications only (with 
m-bib).

Do I have to take care of this manually? If so, and if I don't want
\setupsynonyms[abbreviation][criterium=all],
then
{\setbox0=\hbox{\NMR}}
is an acceptable solution: no output in the dvi file, but context fooled to 
consider the abbreviation used in my text...?
