 ### Rates
-Rate-related properties can currently be specified on `rate` and `time` Rules. Note: A future MDS version will likely support rates for `count` and `speed` rules, but their behavior is currently undefined.
+Rate-related properties can currently be specified on all rule types except `user`, i.e. any rule that can be measured.

 #### Rate Amounts
 The amount of a rate applied when this rule applies, if applicable (default zero). A positive integer rate amount represents a fee, while a negative integer represents a subsidy. Rate amounts are given in the `currency` defined in the [Policy](#policy).
