> We note that there are existing envelope media sizes (iso_c5_162x229mm, iso_c4_229x324mm, iso_c6_114x162mm, jpn_chou3_120x235mm) defined in the IANA registry with the same width and length. However, these media sizes differ in terms of envelope flap position, feed direction, or orientation. We would like to inquire about any concerns or guidelines regarding the registration of identical media sizes with he IANA IPP registry. Your feedback on this matter would be greatly appreciated.

Currently MSN 2.1 does not allow for multiple named sizes to be registered with the same dimensions. We could conceptually relax this for common envelope sizes that are also sheet sizes...

I will add this as a topic of discussion at Thursday's IPP workgroup conference call.
