[IPP] Question for [PWG5100-15, IPP FaxOut Service]

[Walter Zhou]

Hi all,

In page 23 of [PWG5100-15-2014], section 6.1.1 Add-Document-Images 
Request, there is the following description

Group 2: Document Template Attributes
Any Document Template attributes supported by the Printer, to be applied 
to this
hardcopy document.

I am implementing IPP FaxOut, who could give more detail comments for 
the upper description or give some references ?

Regards

Walter
