Hi Michael

Thanks for your comments.

Could you comment on "input-attributes-actual" attribute ? According to 
[PWG5100.15], the attribute could be as both Job Description Attribute 
and Document Description Attribute.

When I implement Add-Document-Image (AddFaxOutHardCopyDocument) 
operation, should I return the attribute in Group 3 (Document 
Description Attributes) ?

And how could I understand it is a Job Description Attribute ? I mean 
under what circumstances, I should return the Job Description Attribute ?
