Internet Printing Protocol (IPP): The 'collection' attribute syntax
R. deBry, Thomas N. Hastings, Robert G. Herriot, K. Ocke, Peter Zehler · 2002
This document specifies an OPTIONAL attribute syntax called 'collection' for use with the Internet Printing Protocol (IPP/1.0 and IPP/1.1). A 'collection' is a container holding one or more named values, which are called member attributes. A collection allows data to be grouped like a PostScript dictionary or a Java Map. This document also specifies the conformance requirements for a definition document that defines a collection attribute. Finally, this document gives some illustrative example collection attribute definitions that are not intended as actual attribute specifications.
