I've had a look at assigning access values and now have the following at

Should this be added to the default style?

I'm sorry - I don't understand what you mean by this. What do you mean
by "If one rule matches, all other unconditional are dropped for the
line"? Can you give an example of a situation where the rules don't
have the desired effect? Maybe there's something I can do to improve
them, or to improve mkgmap - or even to create a separate preprocessor,
if necessary.
If there is a footway with smoothness=very_bad
