Hi,

The draft says:

"Mathematical notation in RFCs will no longer be accepted in Unicode or Scalable 
Vector Graphics (SVGs) for RFCXML or the HTML publication format."

I think that has to be qualified. It could happen that a diagram contains a 
fragment of math notation, for example in the label of the axis of a graph, and 
we don't want to accidentally forbid that.

Hello,

We'd like to allow better mathematical notation in RFCs, so Martin, Lars and I 
put together this policy draft:
https://datatracker.ietf.org/doc/html/draft-rossi-mathinrfcs 
<https://datatracker.ietf.org/doc/html/draft-rossi-mathinrfcs>

The language is very similar to the SVG doc that just made it through AUTH48 
[1].

Please let us know what you think.

If you prefer to use github, the repository is located here:

Thanks,

    mathematical notation in RFCXML and the HTML publication format will
    no longer be accepted in Unicode or Scalable Vector Graphics (SVGs).
