Yes they can be changed. But you only have about ~ 10 levels AFAIK. So 
for some things (but only the most important, like sea, land, forest, 
residential, any others?) - we could say that we put them into even 
every order of 4 levels (and use for each one type - so that makes 16 
types in the typfile.
Then we would say - depending on order, mkgmap chooses one of the types.

mkgmap.

So for a small number of objects, we could indeed use the typfile in 
conjunction with mkgmap to choose the type. In general this is no good 
solution....
