Hi Michael

Thanks for your comment. Your comments are very valuable for my work.

Do you mean I should not return "input-attributes-actual" attribute as Document Description Attribute in Add-Document-Image response ?

Regards

Walter Zhou

Walter,

For implementations that support the document object, input-attributes-actual is reported as a Document Description attribute in response to a Get-Documents or Get-Document-Attributes request.

All implementations can report input-attributes-actual as a Job Description attribute in response to a Get-Jobs or Get-Job-Attributes request.
