And according to the Ethnologue, Walser is another Germanic but
non Alemannic language spoken in Switzerland.  

Rather than using "gem-CH", which could be interpreted in various
ways, why not use the three-letter codes "gsw" for Schwyzerdütsch
and "wae" for Walser as in the proposed/forthcoming ISO 639-3
(and indeed the current edition of the Ethnologue)?
