       ##### Implementation details
       Rule checks for the following conditions:
-        - Exception rule names must start with 'xgen-IPA-' prefix
+        - Exception rule names must start with 'xgen-IPA-' prefix followed by exactly 3 digits
         - Exception rule names can be either short format (xgen-IPA-XXX) or full format (xgen-IPA-XXX-rule-name)
+        - Rule names in full format can use letters (upper/lowercase), numbers, and hyphens
         - Each exception must include a non-empty reason as a string that starts with uppercase and ends with a full stop
         - This rule itself does not allow exceptions
