I had this question come up several times, so let me explain.
Short answer: Kosmos GUI has a feature called "unused ways and nodes"
which (when turned on) allows you to display ( in a visually irritant
way) nodes/ways which were not covered by the rules (see
for more info).
Rules in Kosmos are implemented in such a way as to not exclude each
other. The excluding is only available for child rules. That's why you
cannot set a "default" rule at the end of the ruleset to cover anything
else that wasn't covered by the rules above.
The problem in general is how do you define what's covered and what's
not? Example: you have a node that is a part of the highway. You have
the way covered with a rule, but the node also contains a bus stop tag,
for which you did not set a rendering rule. Is the node covered by rules
Relations make things even more complicated.
> let's suppose I have a ruleset and want to draw anything uncovered by the specific rules as gray symbols or lines. So I want a default rule for nodes and ways not selected by special rules.
