OK - yes 1:200 must be a default? I normally use 1:500. For this system
1:1000 or 1:2000 will be appropriate. Well spotted.

I have never seen 2:<anything> either, so I suppose you are right, but
"scale 1 500" is perhaps more obvious than "scale 500" to a surveyor so
maybe just leave it even though it is not very satisfactory from a
computer-science point of view? I am not sure.

Except now people who _do_ want a tick on every contour will need to add
-tick each time. This doesn't really address the problem of setting defaults
for things like this. Does the UIS symbol set have ticks on contours?

I know defaults should be set by specifying a symbol set, but that is going
to be difficult for 'most users' who don't want to get into writing
MetaPost.  Once we have a wide choice of symbol
sets than most people should be happy I suppose, but I think many surveyors
like to have a few little 'artisitic differences' in their surveys and not
always use _all_ the standard symbols. Something to think about.
