Rule and Rule Set Error Handling
Error handling for rules and rule sets:
Any rule parameter covered in the preceding documentation that has an invalid value will be logged in the rule log as a Warning message. Publishing processing will use the parameter's default value instead.
Any rule parameter that is not recognized by the rule processor will be ignored, presuming the intent is to pass it on to the publishing framework.
Any rule set parameter covered in the preceding documentation that has an invalid value will be logged in the manifest as a Warning message. Publishing rule processing will use the default value instead.
Any rule set parameter not covered in the preceding documentation (not recognized by the rule processor) will be logged in the rule set manifest (if one is generated) as a Warning message.
