Rule Number

The rule must be identified by a rule number and a rule action.  A rule number consists of a prefix and a suffix.  Every rule in the system must have a unique rule number.

Using a prefix and a suffix for rule identification provides flexibility for rules maintenance and retrieval.  Rules are interpreted sequentially within logical levels, therefore you may logically group rules based on prefixes and suffixes. 

Rule inquiries may be based on a partial rule or a prefix.  The prefix of a rule may be specified in rules inquiry, which will result in all rules of the specified prefix being retrieved.
