what are valid options for logging the full content of a message to a remote location?

A: a Multi-Step Log action
B: a Device Log Target with target type of SOAP
C: an Error Rule which contains a Result action that specifies the INPUT context and no destination
D: a Error Rule should be configured in the policy that catches the error code for 'log' action failures
E: a Multi-Step Results action that specifies a destination URL

I see no reference in the documentation:
- ReferenceGuide
- WebGUIGuide

Please can you help.

Thanks, Onno
