John,
I've still got some misgivings about PDF because one of my requirements is to be able to extract things from documents and mark them up.
Good question. I do think that we need the ability to extract material for various purposes, including o Comparisons (rfcdiff etc) o Bis-construction o Verification and statistics tools o Alternative representations (even those offered outside the IETF) Now, I confess that I do not know much about how easy this is from PDF. I suspect its hard... But one way to look at this problem is to say that for you to submit .pdf we need to have your source available as well. And if the source format is standardized, then various operations are possible. --Jari _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
