Rules

This is a flexible resource that can be used to transmit business and system rules from host to client application. These rules may be meant for human consumption (e.g., Real Estate Business Rules (REBR)), in which case the client may be a tool allowing a person to review the business rules. The rules may also be meant for machine consumption (e.g., RETS validation) where the rules are structured to be consumed and executed upon by the client application without human intervention.
