To save time, I would suggest adopting the Patent Office rules on Perpetual Motion. People advocating for a change to facilitate figures (or to allow complicated math, such as tensor analysis) should have an existence proof, i.e., a document that requires the change to be published. (A document that left the IETF to be published elsewhere for this reason would also do.)
RFC1305 which states Note: This document consists of an approximate rendering in ASCII of the PostScript document of the same name. It is provided for convenience and for use in searches, etc. However, most tables, figures, equations and captions have not been rendered and the pagination and section headings are not available. - Stewart _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
