last I knew it was still possible to publish RFCs in PostScript, or
perhaps even PDF, as an alternate to the ASCII version.  I've even had 
reasonable luck with producing I-Ds in multiple formats from the same
revisable source.  it might take a bit of special handling by the RFC
editor but the case you cite seems like adequate justification.
