Mike,
I know it's confusing; it confused some people here. One thing, other
than the inconsistent differences, that contributed to their confusion
was that RFC3382 was publish in September of 2002 and PWG5100.3 was
published in February of 2001. Their initial assumption was that newer
spec should be correct. They did not read the fine print in section 5
that indicates the definitions are informative. Furthermore there is no
reference, normative or informative, that points to the official
definition.
I'd like to see the 6 mistakes in rfc3382 corrected. It might also be a
good idea to include at least an informative reference to PWG5100.3.

Pete,
The media-col definition in 3382 was informative and never registered.
(and yes this is confusing)

All,
The units for media-size in rfc3382 are incorrect. The examples in
rfc3382 are inconsistent. It is my understanding that current
implementations from multiple vendors use hundredth of a millimeter.
Rfc3382:
3.1 4a - example is in mm
5.1.2.1 - defines units as inches
5.1.2.2 - defines units as inches
7.2 - example in inches
Appendix A - example in inches
Appendix B - example in inches
PWG5100.3:
3.13.8.1 - defines units as hundredths of a millimeter
3.13.8.1 - defines units as hundredths of a millimeter
3.13.8.3.1 - defines units as hundredths of a millimeter
3.13.8.3.2 - defines units as hundredths of a millimeter
PWG5105.1:
7.1 - defines units as hundredths of a millimeter (references 5100.3)
PWG5108.1:
4.3.1 - does not call out unit but references 5100.3
5.2.1 - defines units as hundredths of a millimeter (references 5100.3)
