that indeed should be an error. Are all values with "," considered
incorrect? What about 840.8 meters (which is correct english). Basically
any "," should be interpreted as not existent, even though the placement
is not 3 from the right. So I would expect mkgmap to insert 8408 as
height, as we are still using english standards throughout osm, and not
some random local symbols.

That is incorrect tagging. mkgmap does not know what to do with the "m".
Or differently said, mgkamp has no advanced converter to make use of
units like km, m, miles, ....
