Document: draft-faltstrom-base45-10 Reviewer: Robert Sparks Review Date: 2022-02-23 IETF LC End Date: 2022-03-02 IESG Telechat date: Not scheduled for a telechat Summary: Ready for publication as an Informational RFC Note that I have not tried to find a copy of ISO18004:2015. It doesn't seem necessary to read that to build an encoder/decoder as described here. This seems straightforward and appears to have several existing implementations. Should Section 4.1 be titled "When not to use Base45"?
