Add a new Rule to the Ruleset.  Call it “Route Descriptors” and give it the following text:

A rule that defines a Route can contain an explicitly labled list of Tags.  If it does, each Route it defines has those Tags.  If a Route would otherwise have no Tags, it is considered to be GENERIC.  Tags for a Route should be selected from the following list, in accordance with the guidelines presented in that list.
Tags:
*CASH (suitable for Routes whose only effect is to increase the Cash of one or more Drivers)
*AGGRESSIVE (suitable for Routes that have negative effects on other Drivers)
*DEFENSIVE (suitable for Routes that directly mitigate the effects of AGGRESSIVE Routes)
*TEAMWORK (suitable for Routes that have positive effects on other Drivers)

Append the text “Tags: CASH” to the end of the rules “Downtown” “Suburban” and “Airport”.
