Notes:
The "media-col" attribute was defined in PWG 5100.3 (ftp://ftp.pwg.org/pub/pwg/candidates/cs-ippprodprint10-20010212-5100.3.pdf) with units consistent with RFC 3805 - namely hundredths of millimeters. However, since the example in RFC 3382 was for the same attribute, many implementers have made mistakes by using the RFC 3382 example information instead of the normative definitions in PWG 5100.3.
These changes make the example in RFC 3382 match the normative definition in PWG 5100.3.

Section 5 says:
5 Example definition of a collection attribute In some printing environments, it is desirable to allow the client to select the media by its properties, e.g., weight, color, size, etc., instead of by name. In IPP/1.1 (see [RFC2911]), the "media (type3 keyword | name) Job Template attribute allows selection by name. It is tempting to extend the "media" attribute syntax to include "collection", but then existing clients could not understand default or supported media values that use the collection value. To preserve interoperability, a new attribute MUST BE added, e.g., "media-col (collection)". The following subsections contain a sample definition of a simplified "media-col" attribute. The definition follows the rules in section 3.
